BACKGROUND OF INVENTION

1. Probiotic Microorganisms

Probiotic microorganisms are those which confer a benefit when grown ina particular environment, often by inhibiting the growth of otherbiological organisms in the same environment. Examples of probioticorganisms include bacteria and bacteriophages which possess the abilityto grow within the gastrointestinal tract, at least temporarily, todisplace of destroy pathogenic organisms, as well as providing otherbenefits to the host. See e.g., Salminen et al, 1996. Antonie VanLeeuwenhoek 70: 347-358; Elmer et al, 1996. JAMA 275: 870-876; Rafter,1995. Scan. J. Gastroenterol. 30: 497-502; Perdigon et al, 1995. J.Dairy Sci. 78: 1597-1606; Gandi, Townsend Lett. Doctors & Patients, pp.108-110, Jan. 1994; Lidbeck et al, 1992. Eur. J. Cancer Prev. 1:341-353.

The majority of previous studies on probiosis have been observationalrather than mechanistic in nature, and thus the processes responsiblefor many probiotic phenomena have yet to be quantitatively elucidated.Some probiotics are members of the normal colonic microflora and are notreviewed as being overtly pathogenic. However, these organisms haveoccasionally caused infections (e.g., bacteremia) in individuals whoare, for example, immunocompromised. See e.g., Sussman, J. et al., 1998.Rev Infect. Dis. 8: 771-776; Hata, D. et al., 1988. Pediatr. Infect.Dis. 7: 669-671.

For example, the probiotic bacteria found in sour milk, has beenutilized since ancient times (i.e., long-before the discovery ofbacteria) as a therapeutic treatment for dysentery and relatedgastrointestinal diseases. More recently, probiotic preparations weresystematically evaluated for their effect on health and longevity int heearly-1900's (see e.g., Metchinikoff, E., Prolongation of Life, WilliamHeinermann, London 1910), although their utilization has been markedlylimited since the advent of antibiotics int he 1950's to treatpathological microbes. See e.g., Winberg, et al, 1993. Pediatr. Nephrol.7: 509-514; Malin et al, Ann. Nutr. Metab. 40: 137-145; and U.S. Pat.No. 5,176,911. Similarly, lactic acid-producing bacteria (e.g.,Bacillus, Lactobacillus and Streptococcus species) have been utilized asfood additives and there have been some claims that they providenutritional and/or therapeutic value. See e.g., Gorbach, 1990. Ann. Med.22: 37-41; Reid et al, 1990. Clin. Microbiol. Rev. 3: 335-344.

The best known probiotics are the lactic acid-producing bacteria (i.e.,Lactobacilli) and Bifidobacteria, which are widely utilized in yogurtsand other dairy products. These probiotic organisms are non-pathogenicand non-toxigenic, retain viability during storage, and possess theability to survive passage through the stomach and small intestine.Since probiotics do not permanently colonize the host, they need to beingested or applied regularly for any health-promoting properties topersist. Commercial probiotic preparations are generally comprised ofmixtures of Lactobacilli and Bifidobacteria, although yeast such asSaccharomyces have also been utilized.

2. Gastrointestinal Microflora

Perhaps the best-characterized use of probiotic microorganisms is in themaintenance of gastrointestinal microflora. The gastrointestinalmicroflora has been shown to play a number of vital roles in maintaininggastrointestinal tract function and overall physiological health. Forexample, the growth and metabolism of the many individual bacterialspecies inhabiting the gastrointestinal tract depend primarily upon thesubstrates available to them, most of which are derived from the diet.See e.g., Gibson G. R. et al., 1995. Gastroenterology 106: 975-982;Christl, S. U. et al., 1992. Gut 33: 1234-1238. These finding have ledto attempts to modify the structure and metabolic activities of thecommunity through diet, primarily with probiotics which are livemicrobial food supplements.

While the attachment of probiotics to the gastrointestinal epithelium isan important determinant of their ability to modify host immunereactivity, this is not a universal property of Lactobacilli orBifidobacteria, nor is it essential for successful probiosis. See e.g.,Fuller, R., 1989. J. Appl. Bacteriol. 66: 365-378. For example,adherence of Lactobacillus acidophilus and some Bifidobacteria to humanenterocyte-like CACO-2 cells has been demonstrated to prevent binding ofenterotoxigenic and enteropathogenic Escherichia coli, as well asSalmonella typhimurium and Yersinia pseudotuberculosis. See e.g.,Bernet, M. F. et al., 1994. Gut 35: 483-489; Bernet, M. F. et al., 1993.Appl. Environ. Microbiol. 59: 4121-4128.

While the gastrointestinal microflora presents a microbial-based barrierto invading organisms, pathogens often become established when theintegrity of the microbiota is impaired through stress, illness,antibiotic treatment, changes in diet, or physiological alterationswithin the gastrointestinal tract. For example, Bifidobacteria are knownto be involved in resisting the colonization of pathogens in the largeintestine. See e.g., Yamazaki, S. et al., 1982. Bifidobacteria andMicroflora 1: 55-60. Similarly, the administration of Bifidobacteriabreve to children with gastroenteritis eradicated the causativepathogenic bacteria (i.e., Campylobacter jejuni) from their stools (seee.g., Tojo, M., 1987. Acta Pediatr. Jpn. 29: 160-167) andsupplementation of infant formula milk with Bifidobacteria bifidum andStreptococcus thermophilus was found to reduce rotavirus shedding andepisodes of diarrhea in children who were hospitalized (see e.g.,Saavedra, J. M., 1994. The Lancet 344: 1046-109.

In addition, some lactic acid producing bacteria also producebacteriocins which are inhibitory metabolites which are responsible forthe bacteria's anti-microbial effects. See e.g., Klaenhammer, 1993. FEMAMicrobiol. Rev. 12: 39-85; Barefoot et al., 1993. J. Diary Sci. 76:2366-2379. For example, selected Lactobacillus strains which produceantibiotics have been demonstrated as effective for the treatment ofinfections, sinusitis, hemorrhoids, dental inflammations, and variousother inflammatory conditions. See e.g., U.S. Pat. No. 5,439,995.Additionally, Lactobacillus reuteri has been shown to produceantibiotics which possess anti-microbial activity against Gram negativeand Gram positive bacteria, yeast, and various protozoan. See e.g., U.S.Pat. Nos. 5,413,960 and 5,439,678.

Probiotics have also been shown to possess anti-mutagenic properties.For example, Gram positive and Gram negative bacteria have beendemonstrated to bind mutagenic pyrolysates which are produced duringcooking at a high temperature. Studies performed with lacticacid-producing bacteria has shown that these bacteria may be eitherliving or dead, due to the fact that the process occurs by adsorption ofmutagenic pyrolysates to the carbohydrate polymers present in thebacterial cell wall. See e.g., Zang, X. Bacillus et al., 1990. J. DiarySci. 73: 2702-2710. Lactobacilli have also been shown to possess theability to degrade carcinogens (e.g., N-nitrosamines_, which may servean important role if the process is subsequently found to occur at thelevel of the mucosal surface. See e.g., Rowland, I. R. and Grasso, P.,Appl. Microbiol. 29: 7-12. Additionally, the co-administration oflactulose and Bifidobacteria longum to rats injected with the carcinogenazoxymethane was demonstrated to reduce intestinal aberrant crypt foci,which are generally considered to be pre-neoplastic markers. See e.g.,Challa, A. et al., 1997. Carcinogenesis 18: 5175-21. Purified cell wallsof Bifidobacteria may also possess anti-tumorigenic activities in thatthe cell wall of Bifodobacteria infantis induces the activation ofphagocytes to destroy growing tumor cells. See e.g., Sekine, K. et al.,1994. Bifidobacteria and Microflora 13: 65-77. Bifidobacteria probioticshave also been shown to reduce colon carcinogenesis induced by1,2-dimethylhydrazine in mice when concomitantly administered withfructo-oligosaccharides (FOS; see e.g., Koo and Rao, 1991. Nutrit. Rev.51: 147-146), as well as inhibiting liver and mammary tumors in rats(see e.g., Reddy and Rivenson, 1993. Cancer. Res. 53: 3914-3918).

It has also been demonstrated that the microbiota of thegastrointestinal tract affects both mucosal and systemic immunity withinthe host. See e.g., Famularo, G. et al., Stimulation o f Immunity byProbiotics. In: Probiotics: Therapeutic and Other Beneficial Effects.pg. 133-161. (Fuller, R., ed. Chapman and Hall, 1997). The intestinalepithelial cells, blood leukocytes, B- and T-lymphocytes, and accessorycells of the immune system have all been implicated in theaforementioned immunity. See e.g., Schiffrin, E. J. et al., 1997. Am. J.Clin. Nutr. 66: 5-20S. Other bacterial metabolic products which possessimmunomodulatory properties include: endotoxic lipopolysaccaride,peptidoglycans, and lipoteichoic acids. See e.g., Standiford, T. K.,1994. Infect. Linmun. 62: 119-125. Accordingly, probiotic organisms arethought to interact with the immune system at many levels including, butnot limited to: cytokine production, mononuclear cell proliferation,macrophage phagocytosis and killing, modulation of autoimmunity,immunity to bacterial and protozoan pathogens, and the like. See e.g.,Matsumara, K. et al., 1992. Animal Sci. Technol. (Jpn) 63: 1157-1159;Solis-Pereyra, B. and Lemmonier, D., 1993. Nutr. Res. 13: 1127-1140.Lactobacillus strains have also been found to markedly effect changes ininflammatory and immunological responses including, but not limited to,a reduction in colonic inflammatory infiltration without eliciting asimilar reduction in the members of B- and T-lymphocytes. See e.g., DeSimone, C. et al., 1992. Immunopharmacol. Immunotoxicol. 14: 331-340.

3. Physiological Effects of Antibiotic Administration

Antibiotics are widely used to control pathogenic microorganisms in bothhumans and animals. Unfortunately, the widespread use of anti-microbialagents, especially broad spectrum antibiotics, has resulted in a numberof serious clinical consequences. For example, the indiscriminate use ofthese chemicals has resulted in the generation of multipleantibiotic-resistant pathogens. See e.g., Mitchell, P. 1998. The Lancet352: 462-463; Shannon, K., 1998. The Lancet 352: 490-491. The initialreports of Meticillin-resistant Staphylococcus aurous (MRSA) infectionshave been over-shadowed by the recent outbreaks of Vancomycin-resistantEnterococci (VRE). The development of such resistance has led tonumerous reports of systemic infections which remained untreatable withconventional antibiotic therapies. Recently, a Vancomycin—(generallyregarded as the antibiotic of last resort) resistant strain ofStaphylococcus aurous was responsible for over 50 deaths in a singleAustralian hospital.

Enterococci are currently a major nosocomial pathogen and are likely toremain as such for a long period of time. Enterococci, as well as othermicrobes, obtain antibiotic resistance genes in several different ways.For example, Enterococci emit pheromones which cause them to become“sticky” and aggregate, thus facilitating the exchange of geneticmaterial, such as plasmids (autonomously replicating, circular DNA whichoften carry the antibiotic resistance genes). In addition, someEnterococci also possess “conjugative transposons” which are DNAsequences that allow them to directly transfer resistance genes withoutplasmid intermediary. It is believed that penicillin resistance has beenconferred from Enterococci to Streptococci to Staphylococci through thislater mechanism.

In addition, antibiotics often kill beneficial, non-pathogenicmicroorganisms (i.e., flora) within the gastrointestinal tract whichcontribute to digestive function and health. Accordingly, relapse (thereturn of infections and their associated symptoms) and secondaryopportunistic infections often result from the depletion of lacticacid-producing and other beneficial flora within the gastrointestinaltract. Most, if not all, lactic acid-producing or probiotic bacteria areextremely sensitive to common antibiotic compounds. During a normalcourse of antibiotic therapy, many individuals develop a number ofdeleterious physiological side-effects including: diarrhea, intestinalcramping, and sometimes constipation. These side-effects are primarilydue to the non-selective action of antibiotics, as antibiotics do notpossess the ability to discriminate between beneficial, non-pathogenicand pathogenic bacteria, both bacterial types are killed by theseagents. Thus, individuals taking antibiotics offer suffer fromgastrointestinal problems as a result of the beneficial microorganisms(i.e., intestinal flora), which normally colonize the gastrointestinaltract, being killed or severely attenuated. The resulting change in thecomposition of the intestinal flora can result in vitamin deficiencieswhen the vitamin-producing intestinal bacterial are killed, diarrhea anddehydration and, more seriously, illness should a pathogenic organismovergrow and replace the remaining beneficial gastrointestinal bacteria.

In addition to the gastrointestinal microflora, beneficial and/orpathological microorganisms can also inhabit the oral cavity, thegenital area and the vagina (see e.g., Thomason, et al, 1991. Am. J.Obstet Gynecol. 165: 1210-1217; Marsh, 1993. Caries Res. 27: 72-76;Lehner, 1985. Vaccine 3: 65-68; Hill & Embil, 1986. Can. Med. Assoc. J.134: 321-331). The use of anti-microbial drugs can similarly cause animbalance in those microorganisms and the therapeutic use of probioticbacteria, especially the Lactobacillus strains, which colonize thoseareas has been disclosed (see e.g., Winberg, et al., 1993. Pediatric.Nephrol. 7: 509-514; Malm, et al., 1996. Ann. Mar. Metab. 40: 137-145,U.S. Pat. No. 5,176,911). Increasing numbers of pathogenicmicroorganisms have developed antibiotic resistance, requiring thedevelopment and use of second and third generation antibiotics.Microorganisms that are resistant to multiple drugs have also developed,often with multiple drug resistance spreading between species, leadingto serious infections that cannot be controlled by use of antibiotics.

In addition, opportunistic microbial infections often occur inimmunodeficient individuals. Immunodeficient individuals have impairednatural immunity allowing pathogenic microorganisms to survive and grow,either internally or externally, due to the individual's diminishedimmune response to the pathogen. Immunodeficiency can result fromgenetic conditions, diseases such as AIDS, or therapeutic treatmentssuch as cancer therapy (chemotherapy or radiation treatment) anddrug-mediated immunosuppression following organ transplant. Inhibitionof pathogenic microorganisms by probiotics is useful for preventing ortreating opportunistic infections, particularly in immunodeficientindividuals.

Accordingly, there is a need for preventive and therapeutic agents thatcan control the growth of pathogenic microorganisms without the use ofantibiotic chemicals to which the microorganisms already are, or maysubsequently become resistant. Probiotics can be applied eitherinternally or externally to restore the balance of beneficialmicroorganisms to pathogens, without concomitantly contributing to theevolution of drug-resistant pathogens. Lactic acid-producing bacteria(e.g., Bacillus, Lactobacillus and Streptococcus species) have been usedas food additives, and there have been some claims that they providenutritional and therapeutic value (see e.g., Gorbach, 1990. Ann. Med.22: 27-41; Reid, et al., 1990. Clin. Microbiol. Rev. 3: 335-344).

In addition, some lactic-producing bacteria (e.g., those use to makeyogurt) have been suggested to have anti-mutagenic and anti-carcinogenicproperties useful in the prevention of human tumors (see e.g.Pool-Zobel, et al., 1993. Nutr. Cancer 20: 261-270; U.S. Pat. No.4,347,240). Some lactic acid-producing bacteria have also beendemonstrated to produce bacteriocins, which are inhibitory metabolitesresponsible for the bacteria's anti-microbial effects (Klaenhammer,1993. FEMS Microbial. Rev. 12: 39-85; Barefoot & Nettles, 1993. J. DairySci. 76: 2366-2379). Selected Lactobacillus strains produce antibioticshave been disclosed as effective for treatment of infections, sinusitis,hemorrhoids, dental inflammations, and other inflammatory conditions(see U.S. Pat. No. 4,314,995). Similarly, Lactobacillus reuteri has beenshown to produce antibiotics with activity against Gram negative andGram positive bacteria, yeast and a protozoan (see U.S. Pat. Nos.5,413,960 and 5,439,678). Lactobacillus casei asp. rhamnosus strainLC-705, DSM 7061, alone or in combination with a Propionibacteriumspecies, in a fermentation broth, has been shown to inhibit yeast andmolds in food and silage (U.S. Pat. No. 5,378,458). Furthermore,anti-fungal Serratia species have been added to animal forage and/orsilage to preserve the animal feed, particularly Serratia rubidaeaFB299, alone or combined with an anti-fungal Bacillus subtilis (strainP3260). See U.S. Pat. No. 5,371,011), whose disclosure is incorporatedherein by reference, in its entirety.

4. Bacillus coagulans

Bacillus coagulans is a non-pathogenic gram positive spore-formingbacteria that produces L(+) lactic acid (dextrorotatory) inhomofermentation. This microorganism has been isolated from naturalsources, such as heat-treated soil samples inoculated into nutrientmedium (see e.g., Bergey's Manual of Systemic Bacteriology, Vol. 2,Sneath, P. H. A., et al., eds., (Williams & Wilkins, Baltimore, Md.,1986)). Purified Bacillus coagulans strains have served as a source ofvarious enzymes including, but not limited to: restriction endonucleases(see U.S. Pat. No. 5,200,336); amylase (see U.S. Pat. No. 4,980,180);lactase (see U.S. Pat. No. 4,323,651); and cyclo-malto-dextringlucano-transferase (see U.S. Pat. No. 5,102,800). Bacillus coagulanshas been used to produce lactic acid (see U.S. Pat. No. 5,079,164). Inaddition, a strain of Bacillus coagulans (designated Lactobacillussporogenes, Sakaguti & Nakayama (ATCC 31284)) has been combined withother lactic acid-producing bacteria and Bacillus natto to produce afermented food product from steamed soybeans (see U.S. Pat. No.4,110,477). Bacillus coagulans strains have also been used as animalfeed additives for poultry and livestock to reduce disease and improvefeed utilization and to, therefore, increase growth rate in the animals(see International Patent Application Nos. WO 9314187 and WO 9411492).

Accordingly, there remains a need for a highly efficacious biorationaltherapy, which functions to mitigate digestive pathogens, in both humansand animals, by the colonization (or re-colonization) of thegastrointestinal tract with probiotic microorganisms, following theadministration of antibiotics, anti-fungal, anti-viral, and similaragents.

5. Dermal Infections

Dermal infections, especially those caused by mycotic pathogens, make-upa considerable percentage of the sale of prescription andover-the-counter medications that are sold annually worldwide. Accordingto the Center for Disease Control and Prevention (CDCP), there iscurrently a dramatic rise in the number of reported mycotic andbacterial skin infections. Annual sales of dermal and cuticularanti-fungal agents is currently exceeding two billion U.S. dollars eachyear. Moreover, dermal mycotic illness was recently shown to beincreasing at a rate of approximately 9% to 15% per annum, dependingupon the specific pathogen and disease. One of the primary factorsresponsible for the growth of these markets is the fact that more fungalpathogens are becoming resistant to the commonly-utilized anti-fungalagents each year. Examples of anti-fungal agents which arecommonly-utilized, include, but are not limited to: Fluconazole(Diflucan®; Pfizer Pharmaceutical), Intraconazole (Sporonox®; JanssenPharmaceutical), Miconazole Nitrate, Ketoconazole, Tolnaftate, Lamasil,Griseofulvin, Amphotercin B, and other compounds and the formulationsthereof.

New generations of anti-fungal and anti-bacterial drugs and preparationsare being developed every year to replace those medication in whichpathogens have become resistant. As the search for more effectiveanti-microbial agents continues, so does the search for “carryingagents” which are utilized to disperse and facilitate penetration ofthese medications through the various dermal and cuticular membranes andtissues. However, to date there has been little success in finding anagent that is able to penetrate dense cuticular material such asfinger/toenails and animal hooves.

Diseases that are most common to human dermal and cuticular membranesinclude: (i) Candidaisis (e.g., caused by Candida albicans, Candidatropicalis, Candida golbratta, Candida parapsilosis); (ii) Tinealdiseases, also known as Athletes Foot (Tinea Pedis), Jock Itch (TineaCruis), Scalp Infection (Tinea Capitis), Ring Worm, and Beard infections(Tinea Barbae), are all caused by the Trichophyton species, including,but not limited to: Trichophyton mentagrophytes; (iii) diseases whichare caused by bacterial pathogens, including, but not limited to:Pseudomonas aeruginosa, Staphylococcus aerues, Staphylococcusepidermidus, and Propionbacterium acnes; and (iv) diseases which arecaused by viral pathogens, including, but not limited to: Herpes simplexI & II, and Herpes zoster. Perhaps one of the most difficult-to-treatdiseases of fungal etiology are fungal infections of the toenail orfingernail (i.e., Onychomycosis) due to the inability of thecurrently-available therapeutic compositions to penetrate the dermis orcuticle. The pathogen most commonly associated with this very difficultto treat disease is Trichophyton rubrum.

In animals, the most common dermal fungal disease is Ring Worm. Inanimal hooves, especially athletic equine, there are several diseases ofthe hoof that are potentially quite serious and difficult to treat,including: White Line Disease (also known as “Seedy Toe”), Hoof Thrush(another yeast- or Candida-related malady), and Drop Sole. In addition,Clubbed Foot is another dental fungal disease that is of significantconcern to the equine industry.

DETAILED DESCRIPTION OF THE INVENTION

The details of one or more embodiments of the invention are set forth inthe accompanying description below. Although any methods and materialssimilar or equivalent to those described herein can be used in thepractice or testing of the present invention, the preferred methods andmaterials are now described. Other features, objects, and advantages ofthe invention will be apparent from the description and from the claims.In the specification and the appended claims, the singular forms includeplural referents unless the context clearly dictates otherwise. Unlessdefined otherwise, all technical and scientific terms used herein havethe same meaning as commonly understood by one of ordinary skill in theart to which this invention belongs. Unless expressly stated otherwise,the techniques employed or contemplated herein are standardmethodologies well known to one of ordinary skill in the art. Theexamples of embodiments are for illustration purposes only. All patentsand publications cited in this specification are incorporated byreference.

As utilized herein, the term “probiotic” refers to microorganisms (e.g.,bacteria, yeast, viruses, and/or fungi) which form, at a minimum, a partof the transient or endogenous flora and, thus, possess a beneficialprophylactic and/or therapeutic effect upon the host organism.Probiotics are generally known to be clinically-safe (i.e.non-pathogenic) by those skilled within the art. Although not wishing tobe bound by any particular mechanism, the probiotic activity of Bacillusspecies is thought to result from competitive inhibition of growth ofpathogens due to superior colonization, parasitism of undesirablemicroorganisms, lactic acid production and/or other extracellularproducts having anti-microbial activity, or combinations thereof.

As utilized herein, the term “microbial” refers to bacteria, yeast,fungi, and/or virus.

The present invention discloses the ability to utilize Bacillus speciesin therapeutic compositions as a probiotic, for the prevention and/orcontrol infections caused by pathogens including, but not limited to,microbial, yeast, fungal, or viral infections. As will be discussedinfra, these compositions can be formulated in a variety ofconfigurations, due to the fact that the bacterium is presented as aviable organism, either as a vegetative cell or as a spore, andcolonizes the tissue of interest. Specifically, the cells/spores may bepresented in therapeutic compositions suited for topical application toa tissue, or in suspensions such as a bath, or on flexible materialssuch as diapers, bandaids, tampons, and like personal articles, alldirected to the objective of introducing the bacteria topically to skinor a mucous membrane tissue.

1. Probiotic, Lactic Acid-Producing Bacillus Strains

By way of example, and not of limitation to any particular mechanism,the prophylactic and/or therapeutic effect of a lactic acid-producingbacteria of the present invention results, in part, from a competitiveinhibition of the growth of pathogens due to: (i) their superiorcolonization abilities; (ii) parasitism of undesirable microorganisms;(iii) the production of lactic acid and/or other extracellular productspossessing anti-microbial activity; or (iv) various combinationsthereof. It should be noted that the aforementioned products andactivities of the lactic acid-producing Bacillus of the presentinvention act synergistically to produce the beneficial probiotic effectdisclosed herein.

A probiotic bacteria which is suitable for use in the methods andcompositions of the present invention: (i) possesses the ability toproduce lactic acid; (ii) demonstrates beneficial function; and (iii) isnon-pathogenic. By way of example and not of limitation, many suitablebacteria have been identified and are described herein, although itshould be noted that the present invention is not to be limited tocurrently-classified bacterial species insofar as the purposes andobjectives as disclosed. The physiochemical results from the in vivoproduction of lactic acid is key to the effectiveness of the probioticlactic acid-producing bacteria of the present invention. Lactic acidproduction markedly decreases the pH (i.e., increases acidity) withinthe local micro-floral environment and does not contribute to the growthof many undesirable, physiologically-deleterious bacteria, fungi, andviruses. Thus, by the mechanism of lactic acid production, the probioticinhibits growth of competing pathogenic bacteria.

Typical lactic acid-producing bacteria useful as a probiotic of thisinvention are efficient lactic acid producers which includenon-pathogenic members of the Bacillus genus which produce bacteriocinsor other compounds which inhibit the growth of pathogenic organisms.Exemplary lactic acid-producing, non-pathogenic Bacillus speciesinclude, but are not limited to: Bacillus coagulans; Bacillus coagulansHammer; and Bacillus brevis subspecies coagulans.

Several Bacillus species which are preferred in the practice of thepresent invention, include, but are not limited to the lacticacid-producing Bacillus coagulans and Bacillus laevolacticus. Variousother non-lactic acid-producing Bacillus species may be utilized in thepresent invention so long as they produce compounds which possess theability to inhibit pathogenic bacterial or mycotic growth. Examples ofsuch suitable non-lactic acid-producing Bacillus include, but are notlimited to: Bacillus subtilis, Bacillus uniflagellatus, Bacilluslateropsorus, Bacillus laterosporus BOD, Bacillus megaterium, Bacilluspolymyxa, Bacillus licheniformis, Bacillus pumilus, Bacillus mycoides,and Bacillus sterothermophilus.

The Bacillus species, particularly those species having the ability toform spores (e.g., Bacillus coagulans), are a preferred embodiment ofthe present invention. The Bacillus species utilized in the practice ofthe present invention may selected from the group comprising: Bacilluscoagulans, Bacillus subtilis, Bacillus laterosporus and Bacilluslaevolacticus, all of which have the ability to form spores, and cancolonize tissue aerobically. There are a variety of different Bacillusspecies, including, but not limited to many different strains availablethrough commercial and public sources, such as the American TissueCulture Collection (ATCC). For example, Bacillus coagulans strains aleassailable as ATCC Accession Numbers 15949, 8038, 35670, 11369, 23498,51232, 11014, 31284, 12245, 10545 and 7050. Bacillus subtilis strainsare available as ATCC Accession Numbers 10783, 15818, 15819, 297505,13542, 15575, 33234, 9943, 6051a, 25369, 11838, 15811, 27370, 7003,15563, 4944, 27689, 43223, 55033, 49822, 15561, 15562, 49760, 13933,29056, 6537, 21359, 21360, 7067, 21394, 15244, 7060, 14593, 9799, 31002,31003, 31004, 7480, 9858, 13407, 21554, 21555, 27328 and 31524. Bacilluslaterosporus strains are available as ATCC Accession Numbers 6456, 6457,30 29653, 9141, 533694, 31932 and 64, including Bacillus laterosporusBOD. Bacillus laevolacticus strains are available as ATCC AccessionNumbers 23495, 23493, 23494, 23549 and 23492. It should be noted,however, that although many of the examples herein refer to the Bacilluscoagulans species in particular, it is intended that any of the Bacillusspecies can be used in the compositions, articles of manufacture,systems and method of the present invention.

A Bacillus species is particularly suited for the present invention dueto the properties in common between species of the Bacillus genus,including, but not limited to, the ability to form spores which arerelatively resistant to heat and other conditions, making them ideal forstorage (shelf-life) in product formulations, and ideal for survival andcolonization of tissues under conditions of pH, salinity, and the likeon tissues subjected to microbial infection. For example, probioticBacillus coagulans is non-pathogenic and is generally regarded as safe(i.e., GRAS classification) by the U.S. Federal Drug Administration(FDA) and the U.S. Department of Agriculture (USDA), and by thoseindividuals skilled within the art. Additional useful characteristics ofthe Bacillus species include, but are not limited to: non-pathogenicity,being aerobic, facultative and heterotrophic, thus rendering thesespecies safe, and able to colonize skin, mucous membrane tissues, andvarious other tissues of interest.

Because Bacillus species possesses the ability to produce heat-resistantspores, it is particularly useful for making pharmaceutical compositionswhich require heat and pressure in their manufacture. Accordingly,formulations that include the utilization viable Bacillus spores in apharmaceutically-acceptable carrier are particularly preferred formaking and using compositions disclosed in the present invention. Thegrowth of these various Bacillus species to form cell cultures, cellpastes, and spore preparations is generally well-known within the art.It should also be noted that the exemplary culture and preparativemethods which are described herein for Bacillus coagulans may be readilyutilized and/or modified for growth and preparation of the otherBacillus strains, as well as the lactic acid-producing bacteriadisclosed in the present invention. In addition, the exemplary methodsand compositions which are described herein using Bacillus coagulans asa probiotic for controlling, treating, or reducing microbial infections,may also be readily utilized with other Bacillus species.

2. Bacillus coagulans Compositions

Although, as disclosed herein, any of the aforementioned Bacillusstrains may be utilized in the practice of the present invention,purified Bacillus coagulans is exemplary and preferred as a probioticfor biological control of various microbial pathogens. Because Bacilluscoagulans forms heat-resistant spores, it is particularly useful formaking pharmaceutical compositions for treating microbial infections.Topical formulations which include viable Bacillus coagulans spores in apharmaceutically-acceptable carrier, are particularly preferred formaking and using preventive and therapeutic compositions of the presentinvention. The ten “topical” is broadly utilized herein to include bothepidermal and/or skin surfaces, as well as mucosal surfaces of the body.

2.1 Characteristics and Sources of Bacillus coagulans

The Gram positive rods of Bacillus coagulans have a cell diameter ofgreater than 1.0 μm with variable swelling of the sporangium, withoutparasporal crystal production. Bacillus coagulans is a non-pathogenic,Gram positive, spore-forming bacteria that produces L(+) lactic acid(dextrorotatory) under homo-fermentation conditions. It has beenisolated from natural sources, such as heat-treated soil samplesinoculated into nutrient medium (see e.g., Bergey's Manual of SystemicBacteriology, Vol. 2, Sneath, P. H. A. et al., eds., Williams & Wilkins,Baltimore, Md., 1986). Purified Bacillus coagulans strains have servedas a source of enzymes including endonucleases (e.g., U.S. Pat. No.5,200,336); amylase (U.S. Pat. No. 4,980,180); lactase (U.S. Pat. No.4,323,651) and cyclo-malto-dextrin glucano-transferase (U.S. Pat. No.5,102,800). Bacillus coagulans has also been utilized to produce lacticacid (U.S. Pat. No. 5,079,164). A strain of Bacillus coagulans (alsoreferred to as Lactobacillus sporogenes; Sakaguti & Nakayama, ATCC No.31284) has been combined with other lactic acid producing bacteria andBacillus natto to produce a fermented food product from steamed soybeans(U.S. Pat. No. 4,110 477). Bacillus coagulans strains also been used asanimal feeds additives for poultry and livestock to reduce disease andimprove feed utilization and, therefore, to increase growth rate in theanimals (international PCT Patent Applications No. WO 9314187 and No. WO91411492). In particular, Bacillus coagulans strains have been used as ageneral nutritional supplements and agents to control constipation anddiarrhea in humans and animals.

Purified Bacillus coagulans bacteria utilized in the present inventionare available from the American Type Culture Collection (ATCC, 10801University Boulevard, Manassas, Va. 20110-2209) using the followingaccession numbers: Bacillus coagulans Hammer NRS 727 (ATCC No. 11014);Bacillus coagulans Hammer strain C (ATCC No. 11369); Bacillus coagulansHammer (ATCC No. 31284); and Bacillus coagulans Hammer NCA 4259 (ATCCNo. 15949). Purified Bacillus coagulans bacteria are also available fromthe Deutsche Sarumlung von Mikroorganismen und Zellkuturen GmbH(Braunschweig, Germany) using the following accession numbers: Bacilluscoagulans Hammer 1915 (DSM No. 2356); Bacillus coagulans Hammer 1915(DSM No. 2383, corresponds to ATCC No. 11014); Bacillus coagulans Hammer(DSM No. 2384, corresponds to ATCC No. 11369); and Bacillus coagulansHammer (DSM No. 2385, corresponds to ATCC No. 15949). Bacillus coagulansbacteria can also be obtained from commercial suppliers such as SabinsaCorporation (Piscataway, N.J.) or K.K. Fermentation (Kyoto, Japan).

Bacillus coagulans strains and their growth requirements have beendescribed previously (see e.g., Baker, D. et al, 1960. Can. J.Microbiol. 6: 557-563; Nakamura, H. et al, 1988. Int. J. Svst.Bacteriol. 38: 63-73. In addition, various strains of Bacillus coagulanscan also be isolated from natural sources (e.g., heat-treated soilsamples) using well-known procedures (see e.g., Bergey's Manual ofSystemic Bacteriology, Vol. 2, p. 1117, Sneath, P. H. A. et al., eds.,Williams & Wilkins, Baltimore, Md., 1986).

It should be noted that Bacillus coagulans had previously beenmis-characterized as a Lactobacillus in view of the fact that, asoriginally described, this bacterium was labeled as Lactobacillussporogenes (See Nakamura et al. 1988. Int. J. Syst. Bacteriol. 38:63-73). However, initial classification was incorrect due to the factthat Bacillus coagulans produces spores and through metabolism excretesL(+)-lactic acid, both aspects which provide key features to itsutility. Instead, these developmental and metabolic aspects requiredthat the bacterium be classified as a lactic acid bacillus, andtherefore it was re-designated. In addition, it is not generallyappreciated that classic Lactobacillus species are unsuitable forcolonization of the gut due to their instability in the harsh (i.e.,acidic) pH environment of the bile, particularly human bile. Incontrast, Bacillus coagulans is able to survive and colonize thegastrointestinal tract in the bile environment and even grown in the lowpH range. In particular, the human bile environment is different fromthe bile environment of animal models, and heretofore there has not beenany accurate descriptions of Bacillus coagulans growth in humangastrointestinal tract models.

2.2 Growth of Bacillus coagulans

Bacillus coagulans is aerobic and facultative, grown typically innutrient broths, pH 5.7 to 6.8, containing up to 2% (by wt) NaCl,although neither NaCl nor KCl are an absolute requirement for growth. ApH value ranging from approximately pH 4 to pH 6 is optimum forinitiation of sporulation. It is optimally grown at about 30° C. toabout 55° C., and the spores call withstand pasteurization. It exhibitsfacultative and heterotrophic growth by utilizing a nitrate or sulfatesource. Additional metabolic characteristics of Bacillus coagulans aresummarized in FIG. 1.

Bacillus coagulans can be grown in a variety of media, although it hasbeen found that certain growth conditions produce a culture which yieldsa high level of sporulation. For example, sporulation is enhanced if theculture medium includes 10 mg/liter of manganese sulfate, yielding aratio of spores to vegetative cells of about 80:20. In addition, certaingrowth conditions produce a bacterial spore which contains a spectrum ofmetabolic enzymes particularly suited for the present invention (i.e.,the control of microbial infections). Although spores produced by theseparticular growth conditions are preferred, spores produced by anycompatible growth conditions are suitable for producing a Bacilluscoagulans useful in the present invention. It should also be noted thatthe most preferred embodiment of the present invention utilizes Bacilluscoagulans in spore, rather than vegetative bacterial form.

The preparation of a Bacillus coagulans vegetative bacteria and sporeswill be more fully described in the Specific Examples section, infra.

3. Extracellular Products Possessing Anti-Microbial Activity

Bacillus coagulans cultures contain secreted products which possessanti-microbial activity. These secreted products are useful intherapeutic compositions according to the present invention. Cellcultures are harvested as described above, and the culture supernatantsare collected, by filtration or centrifugation, or both, and theresulting supernatant contains anti-microbial activity useful in thetherapeutic compositions of the present invention.

The preparation of a Bacillus coagulans extracellular products will bemore fully described in the Specific Examples section, infra.

4. Probiotic Activity of Bacillus coagulans

It is well-documented clinically that many species of bacterial, mycoticand yeast pathogens possess the ability to cause a variety of disorders.Therefore, the utilization of the probiotic microorganism-containingcompositions of the present invention inhibits these pathogens areuseful in the prophylactic or therapeutic treatment of conditionsassociated with infection by these aforementioned pathogens.

Pathogenic bacteria inhibited by Bacillus coagulans activity include,for example, Staphylococcus aureus, Staphylococcus epidermidus,Streptococcus pyogenes, Pseudomonas aeruginosa, Escherichia coli (i.e.,entero-hemorragic species), numerous Clostridium species (e.g.,Clostridium perfingens, Clostridium botulinum, Clostridium tributrycum,Clostridium sporogenes, and the like); Gardnereia vaginails;Proponbacterium acnes; Aeromonas hydrophia; Aspergillus species; Proteusspecies; and Klebsiella species.

Pathogenic yeast and other fungi inhibited by Bacillus coagulansactivity include Candida albicans, Candida tropicalis and Trichophytonmentagrophytes, Trichophyton interdigitale, Trichophyton rubrum, andTrichophyton yaoundei.

Bacillus coagulans has also been demonstrated to inhibit Herpes simplexviruses I (HSV-I; oral “cold sores” and Herpetic Whitlow) and Herpessimplex II (HSV-II; genital herpes) and Herpes zoster (shingles)infections.

These aforementioned pathogens have been associated with a variety ofdisorders including, but not limited to: diaper rash; oral, genital,cervical and vaginal yeast infections; toxic shock syndrome; chronicmucocutaneous candidaiasis; dermatophytosis; bacterial vaginosis; tinealfungal infections (e.g. ringworm, athlete's foot, and jock itch); scalpand nail fungal infections; superficial skin disorders (e.g.,erysipelas, open-wound infections, acne, abscess, boil, eczema,dermatitis, contact dermatitis, hypersensitinitis, contact lesions, bedsores, and diabetic lesions); miscellaneous opportunistic infection;oral and genital viral lesions, and the like conditions as are wellknown in the art. Therefore, topical use of compositions containing theBacillus coagulans active agents that inhibit these pathogens are usefulin preventing or treating these conditions.

The various pathogens, which may be treated by the use of thetherapeutic compositions of the present invention, and their associateddisorders are illustrated in FIG. 2. It should be noted, however, thatthe pathogens listed in FIG. 2 are set forth as examples only, and arenot meant to be limiting to the types of organisms which can be treatedby use of the methodologies or compositions of the present invention.Accordingly, various other skin- and mucous membrane-infecting microbesand dermatophytes can also be treated by use of the present compositionsand methods disclosed herein.

The aforementioned anti-microbial activity of a therapeutic compositionof the present invention will be more fully-described in the SpecificExamples section, infra.

5. Bifidogenic Oligosaccharides

Bifidogenic oligosaccharides, as designated herein, are a class ofcarbohydrates particularly useful for preferentially promoting thegrowth of a lactic acid-producing bacteria of the present invention.These oligosaccharides include, but are not limited to:fructo-oligosaccharides (FOS); gluco-oligosaccharides (GOS); otherlong-chain oligosaccharide polymers of fructose and/or glucose; and thetrisaccharide-raffinose. All of these aforementioned carbohydrates arenot readily digested by pathogenic bacteria. Thus. the preferentialgrowth of lactic acid-producing bacteria is promoted by the utilizationof these bifidogenic oligosaccharides due to the nutrient requirementsof this class of bacterium, as compared to pathogenic bacteria.

Bifidogenic oligosaccharides are long chain polymers that are utilizedalmost exclusively by the indigenous Bifidobacteria and Lactobacillus inthe intestinal tract and can be similarly utilized by Bacillus. Incontrast, physiologically deleterious bacteria such as Clostridium,Staphylococcus, Salmonella and Escherichia coli cannot metabolize FOS,or other bifidogenic oligosaccharides, and therefor use of thesebifidogenic oligosaccharides in combination with a lactic acid-producingbacteria of the present, preferably Bacillus coagulans, allows thesebeneficial, probiotic bacteria to grow and effectively compete with, andeventually replace any undesirable, pathogenic microorganisms within thegastrointestinal tract.

The use of bifidogenic oligosaccharides in the compositions of thepresent invention provides a synergistic effect thereby increasing theeffectiveness of the probiotic-containing compositions disclosed herein.This synergy is manifested by selectively increasing the ability of theprobiotic bacterium to grow by, for example, increasing the level ofnutrient supplementation which preferentially selects for growth of theprobiotic bacteria over many other bacterial species within the infectedtissue.

In addition, it is readily understood that Bifidobacteria andLactobacillus are also producers of lactic acid. Bifidogenicoligosaccharides enable these aforementioned probiotic organisms toproliferate preferentially over the undesirable bacteria within thegastrointestinal tract, thereby augmenting the probiotic state of thebody by further enhancing the solubility of these nutrients (whether offood origin or as a result of nutritional supplement augmentation).Thus, the presence of the bifidogenic oligosaccharides in thecompositions of the present invention allows for more effectivemicrobial inhibition by increasing the ability of all varieties ofprobiotic bacteria to grow, and therefore provide said benefit.

The bifidogenic oligosaccharide of the present invention may be usedeither alone, or in combination with a lactic acid-producingmicroorganisms in a therapeutic composition. More specifically, due tothe growth promoting activity of bifidogenic oligosaccharides, thepresent invention contemplates a composition comprising a bifidogenicoligosaccharide present in a concentration sufficient to promote thegrowth of lactic acid-producing microorganisms. As shown herein, theseconcentrations amounts can vary widely, as the probiotic microorganismswill respond to any metabolic amount of nutrient oligosaccharide, andtherefore the present invention need not be so limited.

A preferred and exemplary bifidogenic oligosaccharide isfructo-oligosaccharide (FOS), although other carbohydrates may also beutilized, either alone or in combination. FOS can be obtained from avariety of natural sources, including commercial suppliers. As a productisolated from natural sources, the components can vary widely and stillprovide the beneficial agent, namely FOS. FOS typically has a polymerchain length of from about 4 to 200 sugar units, with the longer lengthsbeing preferred. For example, the degree of purity can vary widely solong as biologically-functional FOS is present in the final formulation.Preferred FOS formulations contain at least 50% by weight offructo-oligosaccharides compared to simple (mono or disaccharide) sugarssuch as glucose, fructose or sucrose, preferably at least 80%fructo-oligosaccharides (FOS), more preferably at least 90% and mostpreferably at least 95% FOS. Sugar content and composition can bedetermined by any of a variety of complex carbohydrate-analyticaldetection methods as is well known. Preferred sources of FOS include,but are not limited to: inulin; Frutafit IQ™ (Imperial Suiker Unie;Sugar Land, Tex.); NutraFlora™ (Americal Ingredients, Inc.; Anaheim,Calif.); and Fruittrimfat Replacers and Sweeteners (Emeryville, Calif.).Bifidogenic oligosaccharides such as GOS, and other long chainoligosaccharides are also available from commercial vendors.

In one preferred embodiment, the therapeutic composition of thepresent invention may also include from approximately 10 mg to one gramof a bifidogenic oligosaccharide (e.g., a fructo-oligosaccharide). Theformulation may be completed in total weight by use of any of a varietyof carriers and/or binders. For example, a preferred carrier ismicro-crystalline cellulose (MCC), which is added in a concentrationsufficient to complete the typical one gram dosage total weight.Particularly preferred formulations of the therapeutic composition ofthe present invention will be fully-described in the Specific Examplessection, infra.

The carriers utilized in the therapeutic compositions of the presentinvention may be solid-based, dry materials for use in powderedformulations or, alternately, may be liquid or gel-based materials foruse in liquid or gel formulations.

A therapeutic composition of the present invention may be formulated tobe suitable for application in a variety of manners, for example, in acream for topical application to the skin (e.g., for ringworm orathlete's foot), in a wash for the mouth (e.g., for oral thrush), in adouche for vaginal application (e.g., for vaginitis), in a powder forchaffing (e.g., for dermatitis), in a liquid for toe nails (e.g., fortinea pedis), in a bath salt or bath powder for treating genital, footor other tissue infections in a bath, and the like. Other formulationswill be readily apparent to one skilled in the art and will be discussedmore fully in the Specific Examples section, infra.

6.1 Therapeutic Methods for Treatment of Microbial Infections

The present invention discloses methodologies for treating, reducing,and/or controlling microbial infections in a variety of skin and mucosalmembrane tissues using a therapeutic composition or therapeutic articleof manufacture of this invention. Optimally the compositions effectivelyreduce the bacterial, yeast, fungal and/or viral titer in the treatedindividual, particularly at the site of application of the topicalcomposition. For example, the pathogenic microbial titer in lesions hasbeen demonstrated to be significantly reduced following the topicaladministration of the therapeutic composition of the present inventionto the affected area(s) of the skin or mucous membrane. The disclosedmethods of treatment also reduce symptoms of pathogenic microbialinfection (e.g., pain associated with infected or microbial-causedlesions) and promote more rapid healing than would be found withoutBacillus treatment.

The method of the present invention includes administration of acomposition containing the active Bacillus ingredient to a human oranimal to treat or prevent microbial (i.e., bacterial, yeast, fungal orviral) infection. Administration is preferably to the skin or a mucousmembrane using a cream, lotion, gel, oil, ointment, suspension, aerosolspray, powder, semi-solid formulation (e.g., a suppository), or articleof manufacture, all formulated so as to contain a therapeuticcomposition of the present invention using methods well-known in theart.

Application of the therapeutic composition of the present invention,containing the active Bacillus agent effective in preventing or treatinga microbial infection, generally consists of one to ten applications ofa 10 mg to 10 g concentration of a composition per application, for atime period of one day up to one month. Applications are generally onceevery twelve hours and up to once every four hours. Preferably, two tofour applications of the therapeutic composition per day, of about 0.1 gto 5 g concentration per application, for one to seven days aresufficient to prevent or treat a microbial infection. For topicalapplications, the therapeutic compositions are preferably applied tolesions daily as soon as symptomology (e.g. pain, swelling orinflammation) is detected. The specific route, dosage, and timing of theadministration will the condition.

A preferred methodology involves the application of from approximately1×10³ to 1×10¹² viable bacterium or spores per day, preferably fromapproximately 1×10⁵ to 1×10¹⁰ viable bacterium or spores per day, andmore preferably about from approximately 5×10⁸ to 1×10⁹ viable bacteriumor spores per day. In addition, a preferred method optionally comprisesapplication of a therapeutic composition that additionally contains fromapproximately 10 mg to 20 g of fructo-oligosaccharide (FOS) per day,preferably from approximately 50 mg to 10 g FOS per day, and morepreferably from approximately 150 mg to 5 g of FOS per day, so as topromote the growth of the probiotic Bacillus species over the growth ofthe pathogenic microbe.

With respect to a therapeutic bath, one embodiment of the presentinvention provides for the addition and admixing of a composition of dryBacillus spores (which may additionally contain soaps, oils, fragrances,salts, and the like bath components) to a prepared bath, followed bycontacting the infected tissue(s) to the bath water, as by “taking abath” in the conventional sense. In this embodiment, the therapeutic,probiotic Bacillus spores can be packaged in a system with instructionsas described herein. A typical bath would provide from approximately1×10⁸ to 1×10¹⁰ CFU of bacterial cells or spores per bath, andpreferably from approximately 1×10⁹ to 5×10⁹ CFU of bacterial cells orspores per bath.

Specific methods for the treatment of microbial infections will be morefully described in the Specific Examples section, infra, and include,but are not limited to, the treatment of diaper rash, vaginal yeastinfection, opportunistic skin infection, meal fungal infection,superficial skin infection, acne, cold sores, genital Herpes lesions,Herpetic Whitlow, shingles, athlete's foot, and the like.

One particularly preferred systemcomprises unit dose packages of Bacillus spores for use in combinationwith a conventional bath salt or bath soap product, together withinstructions for using the Bacillus probiotic in a therapeutic method.

6.3 The Utilization of Emu Oil as a Carrier in Therapeutic Compositions

Several animal-derived lipids have been examined for utilization as“carrying agents”, which are used to disperse and facilitate penetrationof these therapeutic compositions through the various dermal andcuticular membranes and tissues. However, prior to the disclosurecontained herein, there has been little success in finding an agent thatis able to penetrate dense cuticular material such as finger/toenailsand animal hooves.

Disclosed herein is the use of an animal-derived lipid, Emu oil, as a“carrying agent” to facilitate the dispersion and penetration of thetherapeutic compositions of the present invention through the variousdermal and cuticular membranes and tissues, and has been demonstrated tomarkedly increase the efficacy of anti-microbial and anti-fungaltherapies. This lipid material is extracted from the Emu (DromaisNovae-Hollandiae), an indigenous bird of Australia and New Zealand.Although Emu oil has been previously described, the uses which aredetailed in these documents elaborate only its benefits as ananti-inflammatory agent for arthritis and its uses for cardiovascularhealth when ingested, which is similar to the use of Omega-3 fish oilsto improve high-density lipoprotein (HDL) cholesterol.

Accordingly, both human and animal diseases, caused by bacterial and/ormycotic dermatophytes, can be mitigated or prevented, whileconcomitantly maintaining dermal and cuticular health, by use of acombination of active agents in a therapeutic composition which includesanti-fungal/anti-bacterial agents (e.g., organic molecules, proteins andcarbohydrates and/or bacterial fermentation products) in combinationwith Emu oil. In a preferred embodiment of the present invention, atherapeutically-effective concentration of Emu oil is combined with thefermentation products of bacteria that have been shown to produceinhibitory metabolites (e.g., Bacillus coagulans) and, optionally, withan anti-microbial agent (e.g., an anti-fungal or antibiotic), in apharmaceutically-acceptable carrier suitable for administration to thedermal and/or cuticular membranes of an animal.

The invention comprisescompositions of a Bacillus and/or isolated Bacillus coagulans activeagent applied to a solid surface or impregnated into a solid matrix ofany device or article of manufacture that is intended to be in contactwith skin or a mucous membrane. Preferably the solid surface is aflexible article than can be worn on or wiped on the skin or mucousmembrane. More preferably, when the flexible item carrying the Bacillusand/or the isolated active agent is to be worn on the skin it includes ameans for attaching the article to the skin such as, for example, anadhesive layer, inter-engaging hook and pile (i.e., Velcro®) connectors,or other well-known means of attachment such as ties, snap closures,elastic, buttons and the like.

Specific embodiments which include Bacillus and/or isolated Bacilluscoagulans active agent are diapers, towelettes (e.g. baby wipes orfeminine hygiene towelettes), tampons, dermal patches adhesive tape,absorbent pads, articles of clothing (e.g., underclothes, sleepingapparel), bath towels, wash cloths, and the like. The article may bemade Of fibrous woven, knitted or non-woven materials, occlusive ornon-exclusive films or membranes, synthetic polymer fibers, films,membranes and foams (e.g., nylon, polytetrafluoroethylene (PTFE, suchTeflon® or Gore-Tex®), polystyrene, polycarbonate, polyvinylchloride andpolysulphone). All of these forms are well-known within the art andinclude, for example, knitted or woven fabrics, non-woven fabrics suchas felt and batting, fiber balls of cotton, rayon, cellulose orsynthetic fibers and the like materials.

The Bacillus and/or Bacillus coagulans isolated active agent can beapplied to the solid surface using any of a variety of known methodsincluding, for example, applying a powder, spray drying the probioticonto the material or soaking the material in a solution containing theprobiotic and then using the wetted material or drying the materialprior to use. Porous material may contain the Bacillus and/or theisolated active agent in the pores or interstices of the solid material.The Bacillus and/or the isolated active agent can be attached byadhesion, such as by attachment to an adhesive layer that is thenapplied to the skin (e.g., in a bandage or dermal patch). The Bacillusand/or the isolated active agent can be impregnated into the solidmaterial during the manufacturing process of the flexible article (e.g.,added to a synthetic composition before or during the polymerizationprocess). The pressure and heat resistance of Bacillus spores makes themparticularly suitable for incorporation into the material duringmanufacturing.

Any of a variety of methods for placing the therapeutic composition ontoa subject article can be used and therefore the invention need not be solimited. However, preferred methods include a “spray-dry” method inwhich the material is exposed in a low humidity chamber to an atomizedmix containing a liquid composition, where the chamber is subsequentlyexposed to approximately 80-110° F. to dry the liquid, therebyimpregnating the material of the article with the components of thecomposition.

A typical concentration is from approximately 1×10⁵ to 1×10⁹ CFU ofviable bacterium or spores/in² of external surface of fibrouscarrier/article material. Following drying, the article is ready forstorage in a sterile package, or for direct use.

7. Specific Examples

The following examples relating to the present invention areillustrative and should not be construed as specifically limiting theinvention. Moreover, such variations of the invention, now known orlater developed, which would be within the purview of one skilled in theart are to be considered to fall within the scope of the presentinvention hereinafter claimed.

7.1 Probiotic Bacillus coagulans Activity

-   -   (A) Anti-Mycotic Probiotic Activity of Bacillus coagulans

The ability of Bacillus coagulans to inhibit various fungal pathogenswas demonstrated using an in vitro assay. In the assay, potato-dextroseplates (DIFCO®, Detroit, Mich.) were prepared using standard proceduresand were inoculated individually with a confluent bed (about 1.7×10⁶) ofvarious species of the fungus Trichophyton. The tested fimgal strains ofTrichophyton species (available from the American Type CultureCollection (ATCC; 10801 University Boulevard, Manassas, Va. 20110-2209))and their ATCC accession numbers, as well as the results of in vitroinhibition by Bacillus coagulans are illustrated in FIG. 3.

Inhibition by Bacillus coagulans as ascertained by placing on the plateapproximately 1.5×10⁶ colony forming units (CFU) in 10 μl of broth orbuffer, plated directly in the center of the potato-dextrose plate, withone test locus per plate. The size of each test locus was approximately8 mm in diameter and a minimum of three tests were performed for eachinhibition assay. The negative control consisted of a 10 ml volume ofsterile saline solution, whereas the positive control consisted of a 10ml volume 2% Miconazole (1-[2-(2,4-dichlorophenyl)-2-[(2,4-dichlorophenyl)methoxylmethyl-1, 11-imidazole within an inertcream.

The plates were then incubated for approximately 18 hr at 30° C., atwhich time the zones of inhibition were measured. As designated herein,“excellent inhibition” means the zone was 10 mm or greater in diameter;and “good inhibition” means the zone was greater than 2 mm in diameter,but less than 10 mn in diameter.

The results of the in vitro inhibition by Bacillus coagulans isillustrated in FIG. 3. For each of the Trichophyton species tested, thedisease condition associated with an infection is indicated in column 2of FIG. 3. For comparison, no zone of inhibition was seen with thenegative control, whereas good inhibition (approximately 8.5 mmdiameter, mean average of three tests) was seen with the positivecontrol.

-   -   (B) Probiotic Inhibition of Yeast by Bacillus coagulans

Similarly, the ability of Bacillus coagulans to inhibit various yeastpathogens was demonstrated in vitro for four species of Candida, all ofwhich are available from the American Type Culture Collection (ATCC;10801 University Boulevard, Manassas, Va. 20110-2209). Each of the yeastpathogens and their ATCC accession numbers are illustrated in FIG. 4.

In the in vitro inhibition assay, potato-dextrose plates (DIFCO®,Detroit, Mich.) were prepared using standard procedures and wereinoculated individually with a confluent bed about 1.7×10⁶ of the fourspecies of Candida. Inhibition by Bacillus coagulans was tested byplacing on the plate about 1.5×10⁶ colony units (CFU) in 10 μl of brothor buffer, plated directly in the center of the potato-dextrose platewith one test locus of about 8 mm in diameter per plate. A minimum ofthree tests were performed for each inhibition assay. The negativecontrol consisted of a 10 μl volume of a sterile saline solution,whereas the positive control consisted of a 1 μl volume of Miconazolecream.

The plates were then incubated for approximately 18 hr at 30° C., atwhich time the zones of inhibition were measured. As designated herein,“excellent inhibition” means the zone was 10 mm or greater in diameter;and “good inhibition” means the zone was greater than 2 mm in diameter,but less than 10 mm in diameter.

The results of the in vitro tests are shown in FIG. 4 with thepathological conditions in humans associated with infection by theCandida species shown in column 2. As expected, no inhibition was seenwith the negative control and good inhibition (approximately 8.7 mmdiameter; average of three tests) was seen with the positive control.

(C) Anti-Microbial Probiotic Activity of Bacillus coagulans

The ability of Bacillus coagulans to inhibit various opportunisticbacterial pathogens was quantitatively ascertained by use of an in vitroassay. This assay is part of a standardized bacterial pathogen screen(developed by the U.S. Food and Drug Administration(FDA)) and iscommercially available on solid support disks (DIFCO® BACTROL® DiskSet). To perform the assay, potato-dextrose plates (DIFCO®) wereinitially prepared using standard procedures. The plates were thenindividually inoculated with each of the bacteria (approximately 1.5×10⁶CFU) to be tested, so as to form a confluent bacterial bed.

Inhibition by Bacillus coagulans was subsequently ascertained by placingapproximately 1.5×10⁶ CFU of Bacillus coagulans in 10 μl of broth orbuffer, directly in the center of the potato-dextrose plate, with onetest locus being approximately 8 mm in diameter per plate. A minimum ofthree test loci were used for each assay. The negative control consistedof a 10 μl volume of a sterile saline solution, whereas the positivecontrol consisted of a 10 μl volume of glutaraldehyde. The plates werethen incubated for approximately about 18 hr at 30° C., at which timethe zones of inhibition were measured. As designated herein, “excellentinhibition” means the zone was 10 mm or greater in diameter, and “goodinhibition” means the zone was greater than 2 mm in diameter but lessthan 10 mm in diameter.

As expected, no “inhibition” was seen with the negative, saline control,and excellent “inhibition” (approximately 16.2 mm diameter; average ofthree tests) was seen with the positive, glutaraldelhyde control. Forthe enteric microorganisms tested, the following inhibition by Bacilluscoagulans was found: (i) Clostridium species—excellent inhibition; (ii)Escherichia coli—excellent inhibition; (iii) Clostridiumspecies—excellent inhibition, where the zone of inhibition wasconsistently greater than 15 mm in diameter. Similarly, excellentinhibition was also seen for the opportunistic pathogens Pseudornonasaeruginosa and Staphylococcus aereus.

In summation, pathogenic enteric bacteria which were shown to beinhibited by Bacillus coagulans activity include, but are not limitedto: Staphylococcus aureus; Staphylococcus epidermidus; Streptococcuspyogenes, Pseudomonas aeruginosa; Escherichia coli (entero-hemorragicspecies); numerous Clostridium species (e.g. Clostridium perfingens,Clostridium botulinum, Clostridium tributrycum, Clostridium sporogenes,and the like); Gardnereia vaginails; Proponbacterium aenes; Aeromonashydrophia; Aspergillus species; Proteus species; and Klebsiella species.

7.3 Growth of Bacillus coagulans

Bacillus coagulans is aerobic and facultative, grown typically innutrient broth, pH 5.7 to 6.8, containing up to 2% (wt/vol) NaCl,although neither NaCl nor KCl are an absolute requirement for growth. ApH value ranging from approximately pH 4 to pH 6 is optimum forinitiation of sporulation. It is optimally grown at about 30° C. toabout 55° C., and the spores can withstand pasteurization. It exhibitsfacultative and heterotrophic growth by utilizing a nitrate or sulfatesource.

Bacillus coagulans can be grown in a variety of media, although it hasbeen found that certain growth conditions produce a culture which yieldsa high level of sporulation. For example, sporulation is enhanced if theculture medium includes 10 mg/liter of manganese sulfate, yielding aratio of spores to vegetative cells of about 80:20. In addition, certaingrowth conditions produce a bacterial spore which contains a spectrum ofmetabolic enzymes particularly suited for the present invention (i.e.,the control of microbial infections). Although spores produced by theseparticular growth conditions are preferred, spores produced by anycompatible growth conditions are suitable for producing at Bacilluscoagulans useful in the present invention.

(A) Culture of Vegetative Bacillus coagulans

Bacillus coagulans is aerobic and facultative, and is typically culturedat pH 5.7 to 6.8, in a nutrient broth containing up to 2% (by wt) NaCl,although neither NaCl, nor KCl are required for growth. A pH of about4.0 to about 7.5 is optimum for initiation of sporulation (i.e., theformation of spores). The bacteria are optimally grown at 30° C. to 45°C., and the spores can withstand pasteurization. Additionally, thebacteria exhibit facultative and heterotrophic growth by utilizing anitrate or sulfate source.

Bacillus coagulans can be cultured in a variety of media, although ithas been demonstrated that certain growth conditions are moreefficacious at producing a culture which yields a high level ofsporulation. For example, sporulation is demonstrated to be enhanced ifthe culture medium includes 10 mg/l of MgSO₄ sulfate, yielding a ratioof spores to vegetative cells of approximately 80:20. In addition,certain culture conditions produce a bacterial spore which contains aspectrum of metabolic enzymes particularly suited for the presentinvention (i.e., production of lactic acid and enzymes for the enhancedprobiotic activity and biodegradation). Although the spores produced bythese aforementioned culture conditions are preferred, various othercompatible culture conditions which produce viable Bacillus coagulansspores may be utilized in the practice of the present invention.

Suitable media for the culture of Bacillus coagulans include: PDB(potato dextrose broth); TSB (tryptic soy broth); and NB (nutrientbroth), which are all well-known within the field and available from avariety of sources. In one embodiment of the present invention, mediasupplements which contain enzymatic digests of poultry and/or fishtissue, and containing food yeast are particularly preferred. Apreferred supplement produces a media containing at least 60% protein,and about 20% complex carbohydrates and 6% lipids. Media can be obtainedfrom a variety of commercial sources, notably DIFCO (Newark, N.J.); BBL(Cockeyesville, Md.); Advanced Microbial Systems (Shakopee, Minn.); andTroy Biologicals (Troy, Md.

In a preferred embodiment of the present invention, a culture ofBacillus coagulans Hammer bacteria (ATCC No. 31284) was inoculated andgrown to a cell density of approximately 1×10⁸ to 1×10⁹ cells/ml innutrient broth containing 5.0 g Peptone; 3.0 g Meat Extract; 10-30 mgMnSO₄ and 1,000 ml distilled water, the broth was then adjusted to pH7.0 The bacterial were cultured by utilization of a standard airliftfermentation vessel at 30° C. The range of MnSO₄ acceptable forsporulation was found to be 1.0 mg/l to 1.0 g/l. The vegetativebacterial cells can actively reproduce up to 65° C., and the spores arestable up to 90° C.

Following culture, the Bacillus coagulans Hammer bacterial cells orspores were collected using standard methods (e.g., filtration,centrifugation) and the collected cells and spores may subsequently belyophilized, spray dried, air dried or frozen. As described herein, thesupernatant from the cell culture can be collected and used as anextracellular agent secreted by Bacillus coagulans which possessesanti-microbial activity useful in a formulation of this invention.

A typical yield obtained from the aforementioned culture methodology isin the range of approximately 10⁹-10¹³ viable spores and, moretypically, approximately 10-15×10¹⁰ cells/spores per gram prior to beingdried. It should also be noted that the Bacillus coagulans spores,following a drying step, maintain at least 90% viability for up to 7years when stored at room temperature. Hence, the effective shelf-lifeof a composition containing Bacillus coagulans Hammer spores at roomtemperature is approximately 10 years.

-   -   (B) Preparation of Bacillus coagulans Spores

A culture of dried Bacillus coagulans Hammer bacteria (ATCC No. 31284)spores may be prepared as follows. Approximately 1×10⁷ spores wereinoculated into one liter of culture medium containing: 24 g (wt./vol.)potato dextrose broth; 10 g of an enzymatic-digest of poultry and fishtissue; 5 g of fructo-oligosaccharides (FOS); and 10 g MnSO₄. Theculture was maintained for 72 hours under a high oxygen environment at37° C. so as to produce a culture having approximately 15×10¹⁰cells/gram of culture. The culture was then filtered to remove theliquid culture medium and the resulting bacterial pellet was resuspendedin water and lyophilized. The lyophilized bacteria were ground to a fine“powder” by use of standard good manufacturing practice (GMP)methodologies. The powder is then combined into Formulation 1 orFormulation 4 as described in Specific Example B to form dry powdercompositions.

It should also be noted that the most preferred embodiments of thepresent invention utilizes Bacillus coagulans in spore, rather thanvegetative bacterial form.

7.4 Preparation of B. coagulans and P. lindbergii Extracellular Products

One liter cultures of either Bacillus coagulans or Pseudomonaslindbergii were prepared as described in Example C(i), except that thefructo-oligosaccharide (FOS) was omitted. The culture was maintained for5 days as described, at which time FOS was added at a concentration of 5g/liter, and the culture was continued. Subsequently, 20 ml of carrotpulp was then added at day 7, and the culture as harvested when theculture became saturated (i.e., no substantial cell division).

The culture was first autoclaved for 30 minutes at 250° F., and thencentrifuged at 4000 r.p.m. for 15 mm. The resulting supernatant wascollected and filtered in a Buchner funnel through a 0.8 μm filter. Thefiltrate was collected and further filtered through a 0.2 μm Nalgevacuum filter. The resulting final filtrate was then collected (anapproximate volume of 900 ml) to form a liquid containing anextracellular product which was to be quantitatively analyzed andutilized in the subsequent inhibition studies.

The following methodologies were utilized to characterize thesupernatant.

Liquid Chromatography of Proteins: 20 ml of culture supernatant wasloaded on an analytical Mono 9 chromatography column (Pharmacia)equilibrated in Buffer A (0.25 M Tris HCl; pH 8.0) using a BioCAD Sprintchromatography system (Perseptive Biosystems, Inc.) running at 2 ml/mm.The column was washed with 15 ml of Buffer A and eluted with a lineargradient ranging from 0% B (i.e., Buffer B is an aqueous 3 M NaClsolution) to 40% B, over a time frame of 12 minutes. The column was thenwashed with 100% B for 5 minutes. Subsequently, the column wasre-equilibrated with Buffer A. Absorbance was monitored at 280 mm todetect elution of aromatic amino acids (i.e., Tyrosine) found inbacterial proteins.

The results demonstrate a mixture of proteins, the majority of whichelute at 0.1 M to 0.8 M NaCl, and a minor fraction of material whichelutes at a 3.0 M NaCl concentration. Fractions were collected andsaved, and dialyzed in Spectrapor dialysis membranes (MW “cut-off”approximately 1,000 Daltons) against water, to facilitate subsequentanalysis.

Ultraviolet and Visible Spectroscopy: Different absorbance spectra weredetermined between 200 and 600 mm wavelengths in 1 cm on quartz cuvettesusing a Uvikon 930 scanning spectrophotometer (Kontron Instruments). Thebaseline was determined with water or LB broth culture media (DIFCO).

The results with a water blank show an absorbance peak at 290 nm to 305nm for Bacillus coagulans (see FIG. 5; Panel A) and Pseudomonaslindbergii (see FIG. 5; Panel B), with a significant amount ofadditional absorbing material found between 210 nm and 400 mm. There wasalso demonstrated to be significant absorbance in the UV wavelengths,primarily due to presense of protein. The results with LB broth (seeFIG. 6) show a marked diminution of absorbing material in the 300 nm to440 nm range, but all increase in the higher wavelengths, thus denotingan increase in the highly-conjugated organics (i.e., proteins) with aconsumption of simpler ones (i.e., amino acids). The fact that there islittle change at the wavelengths where proteins specifically absorb isdue to the fact that LB already contains 10 grams of casein hydrolysate(Casainino acids, DIFCO).

SDS Polyacrylainide Gel Electrophoresis: Electrophoresis was performedby the method of Laemmli (see Laemmli, 1970. Nature 227: 680-685) andthe acrylamide gels were poured in 1 mm cassettes (Novex) and runaccording to recommendations of the commercial supplier (i.e., 120volts, for 90 minutes [12% gel] and for 2 hours [16%]). The gels werethen silver stained by the method of Blum, et al. (see Blum, et al.,1987. Electrophoresis 8: 93-99). A 12% acrylamide gel was found to bestresolved the Pseudomonas lindbergii proteins (see FIG. 7); whereas a 16%gel best resolved the Bacillus coagulans proteins (see FIG. 8). Allsamples were dialyzed against water prior to preparation forelectrophoresis so as to ameliorate salt-associated electrophoreticartifacts. Wide range protein markers (BioRad) were used for proteinmolecular weight determination.

The electrophoretic results demonstrated a significant number ofproteinaceous bands in the less-than 4,000 to 90,000 Dalton range forPseudomonas lindbergii and in the less-than 4,000 to 30,000 Dalton rangefor Bacillus coagulans.

High Pressure Liquid Chromatography: Five ml of culture supernatantswere extracted with 2 ml of acetonitrile, benzene, or 24:1(v:v)chloroform:isoamyl alcohol for approximately two hours. The phases wereallowed to separate for four hours and further separated bycentrifugation at 5000× g for 10 minutes. The organic phase was thenfiltered through 0.2 μm PVDF filters (Gehman Aerodisc LC-13) and loadedon an Econosil C-18 10 U HPLC column (Altech) in a mobile phase of 20 mMTris-HCl (pH 7.5). Elution was started after a total of 5 minutes, in a15 minute linear gradient to 60% acetonitrile (ACN) in water. Elutionwas continued for 5 minutes in 60% ACN and the column was then washedand re-equilibrated in 20 mM Tris-HCl (pH 7.5).

The results of reverse-phase HPLC of ACN-extracted Bacillus coagulansand Pseudomonas lindbergii are illustrated in FIG. 9 and FIG. 10,respectively, and demonstrate that increasing the organic character ofthe solvent led to increasingly “organic profiles” in the HPLC (i.e., anincrease in material eluting at higher percentage of ACN) and anincrease in the capture of pigmented molecules (i.e., molecules whichabsorb visible light). These aforementioned molecules will be isolatedand further characterized.

The results of these aforementioned analytical methodologiesdemonstrated that the culture supernatants from both Bacillus coagulansand Pseudomonas lindbergii are very heterogeneous in nature, containinga plurality of proteinaceous and organic molecules. However, themolecules which predominate are the proteins, of which there are a totalof 20 distinct species in each of the samples. These protein species canbe further fractionated by use of ion exchange chromatography, thusallowing additional characterization. Furthermore, there are alsonumerous pigmented molecules (i.e., molecules which absorb visiblelight) that are both highly conjugated (based upon their absorbance athigh wavelengths) and hydrophobic (based upon their preference fornon-polar solvents and retention on the C-18 HPLC column).

Following the aforementioned analysis and characterization, the assayinitially described in Specific Example A(i) utilizing Candida albicans,1 ml of the aforementioned extracellular product was added to the testplate in place of the bacterium. After an identical culture time, a zoneof inhibition of approximately 10 to 25 mm in diameter was observed.These results illustrate the potent anti-microbial activity of theBacillus coagulans extracellular product, which is of “excellent”quality using the terminology set forth in Specific Examples A(i)-(iii).

In an additional assay, a comparison of the anti-mycotic, Fluconazolewith Bacillus coagulans supernatant in the inhibition of variousbacterial, fungal, and yeast species, was performed. As illustrated inFIG. 11, these supernatants were effective in inhibiting a majority ofthe organisms against which they were used. Serial dilutions of theBacillus coagulans supernatant were performed with RPMI medium andinhibition was determined at 80% in accordance with the NCCLS standardfor anti-fungal susceptibility.

Specifically, the results demonstrated that T. rubrum was totallyinhibited by undiluted supernatant, and 1:2, 1:4, 1:8, 1:16, 1:32, 1:64,1:128, and 1:256 serial dilutions, and the organism as 80% inhibited bythe compound diluted 1:512 with RPMI medium. T. mentagrophytes wastotally inhibited by the undiluted supernatant, and 1:2, 1:4, 1:8, and1:16 serial dilutions, and the organism was 80% inhibited by thesupernatant diluted 1:32 with RPMI medium. C. parapsilosis was totallyinhibited by the undiluted supernatant and 1:2, 1:4, 1:8, 1:16, 1:32,1:64, 1:128, and 1:256 serial dilutions, and the organism was 80%inhibited by the supernatant diluted 1:16 with RPMI medium. C. albicanswas totally inhibited by the undiluted supernatant and a 1:2 dilution,and the organism was 80% inhibited by the supernatant diluted 1:4 withRPMI medium. Acremonium sp. was totally inhibited by the undilutedsupernatant and was 80% inhibited by the supernatant diluted 1.2 withRPMI medium. Scopulariopis sp. was 80% inhibited by the undilutedsupernatant, but was uninhibited by any of the serial dilutions of thesupernatant. The supernatant showed no inhibitory activity against C.glabrata, C. krusel, or the two Aspergillus species. Thus, thesupernatant was demonstrated to possess marked inhibitory activity, in awide variety of dilutions, against a majority of the tested organisms.Moreover, the Bacillus coagulans supernatant appeared to be extremelyeffective against dermatophytes (e.g., Trichophyton sp.), which are acausative organism in many mammalian dermal diseases.

In a preferred embodiment of the present invention, the liquidcontaining the extracellular product was formulated into a liquidointment composition for use in direct application onto a tissue using adropper, such as would be convenient to treat a fungal infection of thetoe nail. This liquid ointment was prepared by combining the liquidextracellular product produced above with Emu essential oil in a ratioof approximately 8:2, and trace fragrances were added to produce anaesthetic component.

Alternatively, one may use any liposomal or oil based transdermaldelivery component in place of the Emu oil. The typical ratio ofprobiotic extracellular product to carrier or delivery component is arange of from approximately 1% to 90% probiotic, and preferably isapproximately 10% to 75% probiotic.

7.6 Topical Application to Prevent Diaper Rash

A powder, aerosol spray liquid, or aerosol spray powder containingBacillus coagulans active agent, preferably Bacillus coagulans spores,is applied to diapers by the consumer before use. Alternatively,disposable diapers supplied from the manufacture may contain Bacilluscoagulans active agent, preferably Bacillus coagulans spores,impregnated into the diaper material where it would be adjacent to thechild's skin when in use. When the diaper becomes wetted by urine and/orfecal material, the spores are activated, usually within about twentyminutes. Bacillus coagulans spore germination and Bacillus coagulansgrowth after spore germination produce sufficient anti-fungal, includinganti-yeast, activity to inhibit growth of yeast and fungal organisms inthe diapers and on the child's skin thus preventing diaper rash or otherdiaper-associated opportunistic infections.

Alternatively or in addition to treating diapers with Bacilluscoagulans, the child's skin in the diaper area can be treated with asaturated soft cloth wipe, powder, aerosol spray liquid, aerosol spraypowder, lotion, cream or ointment containing Bacillus coagulans activeagent. Preferably, the Bacillus coagulans formulation is applied to thechild's skin after bathing and/or when the diapers are changed.

Suitable formulations include a powder of talc and optionally fragrance10 containing approximately 1×10⁵ to 1×10¹⁰ Bacillus coagulans sporesper gram. Other suitable powder formulations contains talc, mineral oil,magnesium carbonate, DMDM, hydantoin, and approximately 1×10⁵ to 1×10¹⁰Bacillus coagulans spores per gram of a corn starch and calciumcarbonate powder. An aerosol powder that includes an isobutane or otherwell known propellant made using standard methods is also suitable. Anaerosol spray may be formulated by combining approximately 1×10⁶ to1×10¹¹ Bacillus coagulans spores per gram in isopropyl myristate, about60% (w/w) SD alcohol 40-B, and isobutane as the propellant usingstandard methods. A manual pump spray containing 1×¹⁰ to 1×10¹¹ Bacilluscoagulans spores per gram of a neutral aqueous solution with no chemicalpropellant is also suitable. A suitable spray formulation includesalcohol, glycerin, purified water and methylparaben in addition to theBacillus coagulans probiotic.

An ointment contains cod,liver oil, methylparaben, propylparaben, talc, optional fragrance andapproximately 1×10⁵ to 1×10¹⁰ Bacillus coagulans spores per gram.Another ointment formulation includes petrolatum, water, paraffin,propylene glycol, milk protein, cod liver oil, aloe vera gel, optionalfragrance, potassium hydroxide, methyl paraben, propyl paraben, vitaminsA, D and E and approximately 1×10⁵ to 1×10¹⁰ Bacillus coagulans sporesper gram. A soft cloth pad (i.e., a baby wipe) is soaked in an aqueoussolution (e.g., water, amphoteric 2, aloe vera gel, DMDM, hydantoin oran aqueous solution of 30% to 70% alcohol) and approximately 1×10⁵ to1×10¹⁰ Bacillus coagulans spores per gram.

7.6 Tropical Treatment of Vaginal Yeast Infection

(A) Vaginal Microecology

It is commonly known to those individuals skilled within the relevantarts that lactic acid-producing microorganisms (e.g., Lactobacillus)play an important role in the maintenance of a healthy vaginal ecology.However, the traditional methodologies utilized for the administrationof these biorational materials do not address the numerous modes ofinfection of Candida and Gardnerella species, which can cause seriousdisease.

The vast majority of gynecologists are adamant regarding the risks ofvaginal infections as a result of frequent bathing. Accordingly,gynecologists recommend the use of showers, rather than immersionbathing, to mitigate the probability of developing subsequent vaginalinfections due to the associated disturbances of the “normal,” lacticacid-producing vaginal flora.

(B) Yeast-Mediated Vaginal Infections

Yeast infections or vuvo-vaginal candidaiasis (VVC) is caused by variousspecies of Candida (e.g., primarily Candida albicans). Over 85% of allwomen, at one time or another, suffer from vuvo-vaginal candidaiasis.For example, the market within the United States market for anti-fungalcompounds which may be administered to ameliorate this disease is over$700 million dollars per year, with an associated 9-11% growth rate perannum. Moreover, each year, additional strains of these aforementionedmycotic pathogens are becoming resistant to the commonly utilizedanti-fungal compounds (e.g. Ketoconazole, Miconazole, Fluconazole, andthe like).

Healthy vaginal ecology is primarily dependant upon specific, indigenouslactic acid-producing microorganisms (e.g., Lactobacilli). Hence, therehave been numerous attempts within the prior art to develop productsand/or methodologies which will augment or reestablish these lacticacid-producing bacteria. For example, one product attempted to utilizehydrogen peroxide-(H₂O₂) producing Lactobacilli as a vaginal suppositorytherapy for the amelioration of vaginal yeast infections.

Viability of the microorganisms continues to be the main difficulty inthe use of Lactobacilli for vaginal supplementation, although it hasbeen suggested by many companies that market Lactobacilli vaginalsuppositories that any hardy bacterial strain is sufficient toaccomplish mycotic mitigation within the vagina. However, theseaforementioned companies primarily base their logic and subsequentassertions upon the fact that there are strains of Lactobacillus whichare able to colonize the vagina, and since their strain is a member ofthe genus Lactobacillus then it should be efficacious. Unfortunately,this supposition or deduction could not be more in error. In a recentstudy, which examined the various indigenous species and strains ofLactobacilli which colonized the vaginas of 100 healthy women. Theresults demonstrated that Lactobacillus acidophilus was not the mostcommon species of Lactobacillus isolated from the vaginas of thesewomen, but rather the most common strains were found to be:Lactobacillus jensenii; Lactobacillus gasserii; Lactobacillussalivarius; and Lactobacillus casel.

This aforementioned information, in combination with recent evidencewhich established that hydrogen peroxide (H₂O₂) is a mandatory metabolicby-product for effective bio-augmentation, disproves the previous beliefthat any strain of Lactobacillus is equally efficacious for use in asuppository-based administration format. Thus, these facts demonstratethe continued need for the development of a product for vaginalsupplementation, in combination with all efficacious method ofadministration, which ameliorates the potential physiological problemsassociated with the use of both bath products and bathing, in general.More specifically, this method must contain a strain of lacticacid-producing bacteria which possesses such characteristics as: (i)long-term shelf-life and viability; (ii) a rapid growth rate (i.e., arapid doubling-time); and (iv) a highly efficacious production of lacticacid, so as to produce an acidic environment within the vagina.

(C) Bacterial-Mediated Vaginal Infections

Despite convincing evidence that lower reproductive tract infectionspossess the ability to migrate to the upper reproductive tract andproduce inflammation, stimulate premature labor, and the like, someclinicians still hold to the tenant that lower reproductive tractinfections and bacterial vaginosis are merely “markers” of upperreproductive tract infections.

It should be noted that bacterial vaginosis is not truly anmicroorganism-mediated infection, but instead a microecologic conditionin which there are dramatic alterations in the endogenous vaginalmicroflora. Specifically, bacterial vaginosis involves a reduction inthe overall number of lactic acid-producing bacterial strains, with aconcomitant multi-log population increase in a characteristic set ofmicroflora including, but not limited to: Gardnerella vaginalis, genitalanaerobes, and mycoplasmas. Interestingly, these latter microorganisms,along with Streptococci and Coliforms, are the same species as thosefound in chorioamnionitis.

Additionally, bacterial vaginosis is also associated with increasedconcentrations of bacterial endotoxin, proteases, mucinases, sialidases,IgA proteases, and phospholipases A2 and C in the lower reproductivetract. Both observational and interventional studies have shown that thepresence of bacterial vaginosis in the early stages of pregnancy isassociated with pre-term delivery and in later stages of gestation, withmiscarriage. These studies suggest that bacterial vaginosis is a directcause of adverse outcomes in pregnancy, rather than simply being asurrogate marker. Studies suggest that ascending infection or abnormallower reproductive tract microflora mediate adverse pregnancy outcomes.Similar microbe-host interactions occur in periodontal disease.

Bacterial vaginosis infections can also be mitigated by lacticacid-producing (i.e., probiotic organisms). AS previously discussed, thecause-and-effect relationship in bacterial vaginosis is due to thereduction of lactic acid-producing bacterial strains with the resultingmulti-log increases of to anaerobic microorganisms including, but notlimited to, Gardnerella vaginalis. However, the results of a recent,3900-woman study performed in Denmark demonstrated that absence ofbacterial vaginosis was directly associated with sufficient vaginalcolonization of aerobic lactic acid-producing organisms. In accord,vaginal supplementation with an effective lactic acid-producingbacterial species will serve to address the imbalance between aerobiclactic acid-producing organisms and the anaerobic species implicated inthe etiology of bacterial vaginosis. Such vaginal supplementation mayeither be utilized prophylactically or therapeutically.

It has now been demonstrated that certain species of lacticacid-producing bacteria can be incorporated into highly alkaline, bathproduct compositions. These compositions would prove lethal to almostall other species of lactic acid-producing bacteria including, but notlimited to: Lactobacillus, Bifidiobacterium, Enterococcus, and variousother stains of vegetative cell bacteria.

Administration remains the major problematic issue of vaginalsupplementation and, prior to the present invention, there was along-felt need for an inoculation strategy which made vaginal lacticacid supplementation incidental. The administration of an adequate doseof an effective lactic acid organisms in a bath or shower product wouldthus address some of the vaginal problems associated with frequent andeven occasional bathing, aroma-therapy, sea salt, bath powders, bathgels, bath oils and the like could contain an effective inoculation oflactic acid bacteria for a vaginal application.

The mechanics of this type of administration may be explained in thefollowing manner. After running a warm bath, the woman would add 1-4ounces of the proposed bath product that contains between approximately1×10⁹ to 2.5×10¹⁰ vegetative bacterial cells (or spores, depending onthe specific bacterial strain which is employed) to the water. The womanwould sit in the bath, moving her legs to facilitate vaginalinoculation, for a total of approximately 20 minutes. Subsequently, thistreatment could be repeated on the third day (e.g., in cases of acutevuvo-vaginal candidaiasis (VVC) or bacterial vaginitis (BV)), or on a“regular basis” (i.e., at-least monthly) in order to promote thecontinued stability of the vaginal ecology and microflora. In addition,this methodology should also prove useful in promoting general dermalhealth, as some species of lactic acid-producing bacteria are useful inthe promotion of healthy skin.

Other strains of bacteria that can be used in a bath or shower productsinclude, Bacillus subtilis, Bacillus laterosporus, Bacillusuniflagellatus, Bacillus pumilus, Bacillus sterothermophilus, Bacilluslentus, Bacillus mycoides, Sporolactobacillus sp. Bacillus licehniformisor any other Bacillus species that out-compete pathogens or has beenshown to produce metabolic byproducts that inhibit mycotic or bacterialpathogens. Other attributes that would influence the efficacy of a bathor shower product would include the baro-tolerance (i.e., pressuretolerance), halo-tolerance (i.e., alkaline tolerance) andthermo-tolerance (i.e., heat tolerance) of the specific probioticorganism that is used.

An example Bath Salt formulation (per dosage) of the present inventionis as follows:

Bacillus coagulans 250,000,000 spores (approximately 18 mg) Bath salts(sea & mineral salts) 10 gm Fructo-oligosaccharides (FOS)  1 gmMicro-crystalline cellulose (MCC)  5 gm Fragrance Trace

Bath products, including granulated or powdered bubble bath, bathcrystals, bath salts, bath oils, powders, aerosol microparticulates andthe like, for treatment of vaginal Candida abbicans and/or Candidatropicalis infections may be produced in a variety of formulations whichcontain Bacillus coagulans vegetative bacterial or (preferably) spores.In a preferred embodiment, in which bubble baths, bath crystals, bathsalts, bath oils and the like are placed in bath water, approximately1×10⁹ Bacillus coagulans spores per ml of an oil-based formulation suchas mineral oil, laureth-4, quaternium-18, hectorite, and phenylcarbinol.In a typical bath (approximately 30-100 gallons total volume), a totalof approximately 5×10⁹ Bacillus coagulans spores are utilized. Natural,oil-based formulations, with or without fragrance, containingapproximately 1×10⁹ Bacillus coagulans spores per ml of an oil whichinclude, but are not limited to, olive oil, grape seed oil, sweet almondoil, geranium oil, grapefruit oil, mandarin oil, peppermint oil, variousessential oils (e.g., Rosemary, Lemon, Geranium, Ylang Ylang, Orange,Grapefruit, Fir, Nutmeg, Balsam, Lime, Peppermint, Vanilla, Lavender,Eucalyptus, Almond, Rose, Palmarosa, Olbas, Kukui Nut, Olibanum and thelike), as well as other oils, herbs and materials which are well-knownfor aroma-therapy applications.

In another preferred embodiment, a non-soap emollient cleansercomposition includes sodium octoxynol-2 ethane sulfonate solution inwater, petrolatum, octoxynol-3, mineral oil or lanolin oil, cocamideMEA, optional fragrance, imidazolidinyl urea, sodium benzoate,tetrasodium EDTA, methylcellulose, adjusted to pH 6.5 to 7.5,approximately 1×10⁷ to 1×10¹⁰ Bacillus coagulans spores per gram. Othersuitable cleansers include well-known water-, glycerin-, and sodiumoleate-based formulations, adjusted to a neutral pH 7.0, and containingapproximately about 1×10⁷ to 1×10¹⁰ Bacillus coagulans spores per gram.Hard-milled soaps, made by standard methodologies, may also includeabout 1×10⁷ to 1×10¹⁰ Bacillus coagulans spores per gram, due to thefact that the spores can withstand the pressure and heat necessary forsoap manufacturing.

In yet another preferred embodiment, for a powder-based composition,approximately about 1×10⁹ Bacillus coagulans spores per gm of talc,powdered oatmeal, cornstarch or similar powdered substance are used.

In still another preferred embodiment, a soft, cloth towelette soaked ina solution of water, potassium sorbate, disodium EDTA and containingapproximately 1×10⁶ to 1×10⁹ Bacillus coagulans spores per towelette maybe utilized to clean the external vaginal area. Additional components tothe aforementioned formulation may include DMDM hydantoin, isopropylmyristate, methylparaben, polysorbate 60, propylene glycol,propylparaben or sorbitan stearate. The disposable towelette is used togently wipe the perivaginal area and is then discarded.

In another preferred embodiment, solid vaginal suppositories or insertscontaining approximately 1×10⁸ Bacillus coagulans per inert are utilizedfor mucosal treatment of Candida abbicans and/or Candida tropicalisinfections. Such formulations can be made, for example, from acombination of corn starch, lactose, a metal stearate (e.g., magnesiumstearate) and povidone. Typically, one to three solid inserts should beused per day while symptoms (e.g., vaginal itch and/or whitishdischarge) are detected. Optimally, one insert per day, for a total ofthree to seven days, preferably at bedtimes is used.

In yet another preferred embodiment, for an aerosol-based delivery ofmicroparticulates, an aerosol spray may be formulated by combiningapproximately 1×10⁶ to 1×10¹¹ Bacillus coagulans spores per gm of acarrier mixture which is comprised of isopropyl myristate, approximatelyabout 60% (w/w) alcohol 40-B, and isobutane as the propellant. Anon-aerosol, manual pump spray containing approximately 1×10⁵ to 1×10¹¹Bacillus coagulans spores per gm of a neutral aqueous solution may alsobe utilized. A suitable spray formulation includes alcohol, glycerin,purified water and methylparaben, in addition to the Bacillus coagulansprobiotic microorganism.

It should also be noted that while the mitigation of yeast infections isthe primary vaginal-based utilization of Bacillus coagulans therapeuticcompositions, these compositions have also been demonstrated to behighly effective in the treatment of non-pathogenic, nonspecificdermatitis. Immersion in the therapeutic bathing compositions of thepresent invention allow the establishment of the probiotic Bacilluscoagulans on the skin or mucosal membranes, which tends to mitigatedermatitis of unknown etiology.

7.7 Prevention and/or Treatment of Opportunistic Skin Infections

Opportunistic skin infections with Pseudomonas and or Staphylococcusspecies (i.e., typically Pseudomonas aeruginosa, Staphylococcusepidermidus, Staphylococcus aureus, and the like) commonly occurconcomitantly with skin allergies (e.g., allergic reactions to plantirritants such as poison ivy), bed sores, diabetic lesions or othertypes of skin lesions. Probiotic formulations containing Bacilluscoagulans spores (i.e., approximately 1×10⁵ to 1×10¹⁰/ml depending onthe specific formulation and application) and/or supernatant or filtratecontaining extracellular bacteriocins produced by Bacillus coagulans orPseudomonas lindbergii strains are highly useful in the prevention ortreatment of opportunistic skin pathogens. Additionally, probioticBacillus coagulans formulations are useful in the prevention ofinfection with Meticillin-resistant Staphylococcus aureus (MRSA),particularly following injury or invasive surgical procedures. Awater-in-oil or oil-in-water emulsion, cream, lotion, powder, aerosolpowder, or aerosol spray containing approximately 1×10⁶ to 1×10¹⁰Bacillus coagulans spores/ml is used. Various suitable carriers havebeen previously described herein, and others are well known within theart.

In the practice of this embodiment of the present invention, the skin isinitially cleaned with soap and water and dried thoroughly. The Bacilluscoagulans-containing therapeutic composition is then applied to theskin, ensuring that the composition is applied to the areas between thetoes, under the breasts, under the arms, or any other areas where theskin may become moist or exhibit frictional chafing or abrasion.

In addition to treating the skin topically with an emulsion, cream,lotion, powder, aerosol powder, or aerosol spray containing Bacilluscoagulans probiotic, the skin may be cleansed with a probioticformulation such as described herein.

7.8 Treatment of Tineal Fungal Infections

Ringworm (tinea versicolor) is caused by localized infections of theskin of the trunk and neck by dermatophyte fungus which colonizes theouter layer of the skin resulting in generally circular patches ofwhite, brown or pink flaking skin that are often itchy. Once ringworm isdetected, the affected area and a surrounding approximately 1 to 10 cm²area is treated twice daily with a cream or lotion containing 10% byweight Bacillus coagulans spores. Suitable carriers are describedherein, preferably containing approximately 1×10⁵ to 1×10¹⁰ Bacilluscoagulans spores/ml of carrier.

For treatment of the related disorder, tinea cruris (i.e., “jock itch”),a powder containing approximately 1×10⁷ to 1×10⁹ Bacillus coagulansspores/ml of colloidal silicon dioxide, isopropyl myristate, talc andoptional fragrance is applied to the groin area to provide relief ofitching, chafing, burning rash and irritation. Treatment is twice daily,generally after bathing and at bedtime, until symptoms are no longerdetected.

Clothing, particularly underclothes and nightclothes that come incontact with the trunk and neck are sprayed with an aerosol containingabout 1% to about 20% Bacillus coagulans active agent in a suitablecarrier such as described herein, so as to ameliorate the spread of theinfection to additional areas of the body.

7.9 Treatment of Bacterial and Fungal Infections of the Dermis andCuticle

As previously discussed, various lactic acid-producing bacteria (e.g.Bacillus coagulans and Pseudomonas lindbergii) have been shown toproduce extracellular products that are anti-fungal in nature althoughall of the products that have come from these bacteria are a result ofthe purification of a specific active analog such as a protein,carbohydrate or organic molecule to form a new anti-fungal compound. Ithas been suggested that tile use of a single active agent contributes toresistant species of pathogenic fungi and as a result new generations ofanti-fungal compounds must be discovered in order to control these newdeveloping species. However, the use of a bacterial supernatant in itscrude or in a semi-refined state my be more effective in topicalapplications and may, in fact, decrease the rate of anti-fungalresistance by providing a more complex killing mechanism that is moredifficult to overcome than a single chemical agent or analog.

The use of Emu oil as a “carrier” in the therapeutic compositions of thepresent invention markedly enhances efficacy in the prevention and/ortherapeutic treatment of fungal or bacterial infections of the dermisand cuticle in both humans and animals. These therapeutic compositionsare comprised of the fermentation products of specific bacterial strainsand, optionally, a commercially available antibiotic or anti-fungalagent in combination with an effective amount of Emu oil in apharmaceutically acceptable cater suitable for administration to thedermal and/or cuticular membranes of a human or animal.

In various embodiments of the present invention, the final form of thetherapeutic composition may include, but is not limited to: a stabilizedgel, a lotion, a cream, a semi-solid roll-on stick, a fluid, an aerosol,a spray powder, or an emulsion.

The overall efficacy of the therapeutic compositions of the presentinvention is relative to the concentration of Emu oil which is utilizedin the formulation. Specifically, it has been observed that higherpercentages of Emu oil is more effective than lower percentages. Not tobe bound by any efficacious percentage, the range of Emu oil used in atopical therapeutic composition of the present invention ranges fromapproximately 0.5% to 99.9 %, with a more preferable range being betweenapproximately 10% to 75%, and the most preferable range being betweenapproximately 25% to 60%. The 0.5% to 99.9% ultimate effective range forEmu oil concentration is due to the very small concentrations ofanti-microbial compounds which are typically used in the therapeuticcompositions of the present invention. For example, in a dermalapplication, the anti-fungal agent, Miconazole Nitrate, generallycomprises only 2% of the total formulation. The following are examplesof therapeutic compositions which have been demonstrated to be effectivein the mitigation of bacterial and mycotic diseases of the dermis andcuticle.

Therapeutic Composition No. 1

Miconazole Nitrate, Fluconazole, Tolnaftate,  2% Ketoconazole orIntraconazole Emu oil or Fraction Thereof 90% Emulsifier  5% Fragrance 3%Therapeutic Composition No. 2

Quaternary Ammonium Chloride, Iodine, 10% Alcohol or Phenolic CompoundsEmu Oil or Fraction Thereof 80% Emulsifier  7% Fragrance  3%Therapeutic Composition No. 3

Bacterial Supernatant Composition 50% Fermentation Products Emu Oil orFraction Thereof 40% Emulsifier  7% Fragrance  3%Therapeutic Composition No. 4

Bacterial Supernatant Composition 50% Fermentation Products Emu Oil orFraction Thereof 25% Lavender Oil  2% Hydrosperse Oil 20% EmulsifyingAgents  3%As previously discussed, these aforementioned therapeutic compositionsof the present invention may also be utilized in combination with otheranti-fungal agents, including, but not limited to: Fluconazole,Intraconazole, Ketoconazole, Tolnaftate, Lamasil, Quaternary AmmoniumChlorides, Phenolics, Iodiphers, and the like. In addition, variousother materials (e.g., Titanium oxide) to enhance the whitening of thetoe or finger nail may also be used.

In a specific example, a therapeutic composition of the presentinvention, containing bacterial supernatant derived from Bacilluscoagulans, was used to mitigate the human fungal infection,Onychomycosis. One ml of the aforementioned therapeutic composition wasapplied after bathing to each infected nail. Treatment resulted in achange in the green-to-yellow color of the nail within 10 days, in allindividuals studied. In addition, within the first 7 days, the detritusunder the nail sloughed-off and the thickness of the nail (one of theclinical manifestations of the disease) began to subside. Although thetotal amount of time which was required to ameliorate this diseasevaried between each subject, the average time required ranged from onemonth for superficial infections to six months for more pronouncedOnychomycosis. Also, it must be taken into consideration that cosmeticappearance is an aspect of this disease that is independent of thepathology of the nail bed.

In has been demonstrated that the simultaneous anti-fungal action of thebacterial culture supernatant combined with the dermal-penetrating andhealing aspects of the Emu oil work in a synergistic manner toameliorate the fungal infection. It is generally known that Emu oilpossess the ability to rehydrate skin cells in a way that promotes thegrowth of new cells. Similarly, it is quite possible that Emu oil actsin a similar manner in human nail and cuticular tissues.

In other specific examples, a therapeutic composition of the presentinvention, containing bacterial supernatant derived from Bacilluscoagulans, was also utilized to treat cases of diaper rash which werecomplicated with bacterial or fungal infections. Immediate (i.e.,approximately 18 hours) relief of the dermal inflammation and rednesswas achieved, and all of the infections were completely amelioratedwithin 48 hours. Similar results have been observed in the use of thesetherapeutic compositions in the treatment of Jock itch (Tinea cruris),Ringworm, Athlete's Foot (Tinea pedis), Scalp infections (Tineacapitis), Beard infections (Tinea barbae), Candidaiasis of the dermis,toe, fingernail and vulva, and other dermal and cuticular diseases.

Various equine hoof diseases (e.g., White Line disease, Hoof Thrush,Drop Sole, and even Clubbed Foot) have also responded to the use oftherapeutic compositions of the present invention, containing bacterialsupernatant derived from Bacillus coagulans, the same manner asOnychomycosis in humans. In addition, similar to its physiologicalactivity in humans, Emu oil may also function to rehydrate and stimulatenew cell growth within animal hooves and other cuticular materials.

7.10 Treatment of Superficial Skin Infections

Superficial infections with Staphylococcus species (e.g., Staphylococcusaureus and Staphylococcus epidermidis) of a blocked sweat or sebaceousgland cause pustules, boils, abscesses, styes or carbuncles. Thesesuperficial skin infections may also be accompanied by a blistering rash(particularly in babies), due to bacterial toxins released big theStaphylococcus species.

A water-in-oil or oil-in-water emulsion, cream, lotion, or gel,containing approximately 1×10⁶to 1×10⁹ Bacillus coagulans spores/ml maybe used. An exemplary topical gel is prepared by mixing together equalvolumes of propylene glycol and water, 1% by weight hydroxypropylcellulose (MW of 100,000 to 1,000,000 Daltons) and lyophilized Bacilluscoagulans culture to a final concentration of approximately 1×10⁶ to1×10⁹ Bacillus coagulans spores/ml of the combination, and allowing thestirred mixture to sit for 3 to 5 days to form a gel. Other formulationsare also presented herein.

The Bacillus coagulans-containing emulsion, cream, lotion, or gel isapplied to the area of the skin showing superficial skin infections(e.g., pustules, boils, abscesses, styes or carbuncles) or rash andgently rubbed into the skin and allowed to air-dry. Applications areat-least once per day, and preferably two to three times per day (e.g.,morning and night), or after each washing of the infected area for thoseareas which are washed frequently (e.g., the hands or diaper area).Applications are continued until skin inflammation has subsided and theskin appears normal to the observer.

Alternatively, the skin may be cleansed using any well-known cleanserand then a cream containing an active ingredient derived from a Bacilluscoagulans or Pseudomonas lindbergii culture supernatant or filtrate isapplied to the skin in a thin film about once every two days to aboutthree times daily as needed. A suitable cream includes approximately 10%to 12% alcohol (v/v), bentonite, optional fragrance, iron oxides,potassium hydroxide, propylene glycol, titanium dioxide, purified waterand approximately 0.5% to 60% (v/v) of an aqueous supernatant orfiltrate of a Bacillus coagulans or Pseudomonas lindbergii culture grownto saturation.

The above formulation is suited for treating acne caused byPropionibacterium acne and by Staphylococcus epidermidis.

7.12 Treatment of Herpes simplex I & II and Herpes zoster Infections

Cold sores (generally found within or around the mouth) are caused bythe virus Herpes simplex I; whereas similar lesions around the genitalsare caused by Herpes simples II. Herpes simplex viral infections canalso cause painful finger or toe swelling (i e., Herpetic Whitlow). Bothtypes of Herpes simplex lesions or Whitlow can be treated with a cream,lotion or gel ointment containing approximately 1×10⁷ to 1×10¹⁰ Bacilluscoagulans spores/ml.

For oral cold sores, a soothing emollient lip balm contains allentown,petrolatum, titanium dioxide at cosmetically acceptable levels, andapproximately 1×10⁷ Bacillus coagulans spores/mi. The lip balm mayfurther include a sunscreen (e.g., paginate O). An alternative emollientlip balm contains the same base ingredients mixed to form an emulsionwith approximately 0.5% to 20% (v/v) of an aqueous supernatant orfiltrate of a Bacillus coagulans culture grown to saturation. Tile lipbalm is then applied to the lips and affected area to form a light filmas a prophylactic when prodromal symptoms are felt (e.g., tingling,itching, burning) or when a lesion is visible. The lip balm should beapplied as often as required (e.g., every hour when a lesion is present)and generally once per day at bedtime.

For oral cold sores, the Bacillus coagulans spores or extracellularagent in culture supernatant or filtrate may be formulated into asemisolid lip balm containing approximately 20% to 40% white petrolatum,wax paraffin, mineral oil, isopropyl lanolate, camphor, lanolin,isopropyl myristate, cetyl alcohol, carnuba wax, methylparaben,propylparaben, titanium, dioxide and optionally fragrance and coloringagents.

For genital herpes lesions, a cream or ointment is formulated usingstandard methods as described herein containing approximately ×10⁷ to1×10¹⁰ Bacillus coagulans spores/ml and/or approximately 0.5% to 20%(v/v) of an aqueous supernatant or filtrate of a Bacillus coagulansculture grown to saturation. The cream or ointment is applied at leasttwice daily as needed.

For lesions caused by Herpes zoster (i.e., shingles) a cream or ointmentis formulated using standard methods as described herein containingapproximately 1×10⁷ to 1×10¹⁰ Bacillus coagulans spores/mil and/orapproximately 0.5% to 20% (v/v) of an aqueous supernatant or filtrate ofa Bacillus coagulans or Pseudomonas lindbergii culture grown tosaturation. The cream or ointment is applied at least twice daily asneeded.

7.13 Ear Drops or Ear Wash Containing Bacillus coagulans Spores

For the prevention or treatment of external ear canal infections, anaqueous formulation that includes approximately 1×10⁵ to 1×10⁸ Bacilluscoagulans spores/ml and/or approximately 0.1% to 15% (v/v) of an aqueoussupernatant or filtrate of a Bacillus coagulans or Pseudomonaslindbergii culture grown to saturation, is utilized. The spores and/orsupernatant is added to a sterile aqueous solution containingapproximately 5% to 50% glycerin (v/v), approximately 0.1% to 5%propylene glycol (v/v), and sodium stannate or sodium chloride. Allalternative formulation includes approximately 1×10⁵ to 1×10⁸ Bacilluscoagulans spores/ml, and/or approximately 0.1% to 15% (v/v) of allaqueous supernatant or filtrate of a Bacillus coagulans or Pseudomonaslindbergii culture grown to saturation in a sterile aqueous solution ofapproximately 0.5% to 25% glycerin (v/v), approximately 5% to 10%alcohol (v/v), and polysorbate 20.

To apply the formulation, the user tilts the head sideways and about 3to 10 drops of the aforementioned ear formulation is added to the earusing a standard dropper applicator, without having the applicatoractually enter the external ear canal. The head is kept tilted forseveral minutes or, alternately, the ear may be lightly plugged with awad of cotton so as to allow the solution to remain in the ear for up to15 minutes. Then the head is then tilted, and excess solution is allowedto drain from the ear. Gentle washing with an ear syringe containingwarm water may also be utilized to remove the excess formulation. Theprobiotic solution can be applied occasionally or daily for up toapproximately five days in-total. The accompanying instructions indicatethat a physician should be consulted if there is drainage, discharge,rash, severe irritation in the ear, or if the patient experiencesdizziness.

7.14 Prophylactic or Therapeutic Treatment of Athlete's Foot

For the prevention or therapeutic treatment of athlete's foot (i.e.,tineal fungal infection), the feet are washed with soap and water, driedthoroughly and a powder, cream, lotion, ointment or gel, such as thosedescribed in the above examples is applied to the entire foot area.Preferably, the formulation includes approximately 1×10⁵ to 1×10⁸Bacillus coagulans spores/ml and/or approximately 0.5% to 20% Bacilluscoagulans supernatant or filtrate of a Bacillus coagulans or Pseudomonaslindbergii culture grown to saturation. Dailey treatments are continuedas needed.

Additionally, athlete's foot may be prevented or treated by using astandard insole inert (e.g., a fabric, fiber or synthetic foam) havingsprayed on the surface or impregnated therein with the Bacilluscoagulans probiotic or extracellular anti-fungal product. Such treatedinsoles may be worn daily for up to two to three months after which theyare discarded and replaced with fresh treated insoles.
